[R] How numerical data is stored inside ts time series objects
I'm getting familiar with the stl function in the stats packcage by
trying it on an example from Brockwell Davis's 2002 Introduction to
Times Series and Forcasting. Specifically, I'm using a subset of his
red wine sales data. It's a detour from the stl material at
http://www.stat.pitt.edu/stoffer/tsa3/R_toot.htm (at some point, I
have to stop simply following and try to make it work with new data).
I need a minimum of 36 wine sales data points in the series, since stl
otherwise complains about the data being less than 2 cycles. The data
is in ~/tmp/wine.txt:

My sourced test code is buried in a repeat loop so that I can use a
break command to circumvent the final error-causing statement that I'm
trying to figure out:
repeat{
# Clear variables (from stackexchange)
rm( list=setdiff( ls( all.names=TRUE ), lsf.str(all.names=TRUE ) ) )
ls()
head( wine - read.table(~/tmp/wine.txt) )
( x - ts(wine[[1]],frequency=12) )
( y - ts(wine,frequency=12) )
( a=stl(x,per) )
#break
( b=stl(y,per) )
}
The final statement causes the error 'Error in stl(y, per) : only
univariate series are allowed'. I found an explanation at
http://stackoverflow.com/questions/10492155/time-series-and-stl-in-r-error-
only-univariate-series-are-allowed.
That's how I came up with the assignment to x using wine[[1]]. I
found an explanation to the need for
double square brackets at
http://www.r-tutor.com/r-introduction/list/named-list-members.
My problem is that it's not very clear what is happening inside the ts
structures x and y. If I simply print them, they look 100% identical:

Whatever their differences, it's not causing R to misinterpret the
data; that is, they each look like in single series of numerical data.
Can anyone illuminate the difference in the data inside the ts data
structures? The potential incompatibility with stl is just one
symptom. Right now, the solution is black magic to me, and I would
like to get a clearer picture so that I know when else (and how) to
watch out for this.

Re: [R] How numerical data is stored inside ts time series objects
Use the str() function to see the internal structure of most objects. In
your case it would show something like:
Data - data.frame(theData=round(sin(1:38),1))
x - ts(Data[[1]], frequency=12) # or Data[,1]
y - ts(Data, frequency=12)
str(x)
Time-Series [1:38] from 1 to 4.08: 0.8 0.9 0.1 -0.8 -1 -0.3 0.7 1 0.4 -0.5
...
str(y)
ts [1:38, 1] 0.8 0.9 0.1 -0.8 -1 -0.3 0.7 1 0.4 -0.5 ...
- attr(*, dimnames)=List of 2
..$ : NULL
..$ : chr theData
- attr(*, tsp)= num [1:3] 1 4.08 12
'x' contains a vector of data and 'y' contains a 1-column matrix of data.
stl(x,per) and stl(y, per) give similar results as you got.
Evidently, stl() does not know that 1-column matrices can be treated much
the same as vectors and gives an error message. Thus you must extract
the one column into a vector: stl(y[,1], per).

Re: [R] high density plots using lattice dotplot()
Hi Luigi
Strips take up space so if you are willing to not have strip and put the
strip values within the plot area then
xyplot(y ~ x|cond.factor, data = ...,
as.table = T,
groups = ...,
layout = ...,
drop.unused = T,
par.settings = list(axis.text = list(cex = 0.6),
par.xlab.text = list(cex = 0.75),
par.ylab.text = list(cex = 0.75)
superpose.symbol = list(pch = ., cex = 2)
),
strip= FALSE,
scales = list(x = list(alternating = 2),
y = list(alternating = FALSE)
),
type = p,
panel = function(x,y, subscripts, groups,...){
panel.superpose(x,y,subscripts,groups,...,
col = ...)
panel.text(x,y,...,cex = 0.6)
}
)
if the text values are a vector
stext = ...
xyplot(y ~ x|cond.factor, data = ...,
as.table = T,
groups = ...,
layout = ...,
drop.unused = T,
par.settings = list(axis.text = list(cex = 0.6),
par.xlab.text = list(cex = 0.75),
par.ylab.text = list(cex = 0.75)
superpose.symbol = list(pch = ., cex = 2)
),
strip= FALSE,
scales = list(x = list(alternating = 2),
y = list(alternating = FALSE)
),
type = p,
panel = function(x,y, subscripts, groups,...){
pnl = panel.number()
panel.superpose(x,y,subscripts,groups,...,
col = ...)
panel.text(x,y,stext[pnl],cex = 0.6)
}
)
you could also you group.number instead of pnl if it is needed elsewhere.
text position could be done in a similar fashion if needed to be in
different places for some panels.
If you require the strip then an additional par.settings is
layout.heights = list(strip = 0.8)
or even untested in this situation
strip = FALSE
strip.left = TRUE

Subject: [R] high density plots using lattice dotplot()
Dear all,
I am trying to plot the results of a PCR experiments that involves 384
individual plots. Admittedly the space for the plots will be tiny, but
I just nedd some icon to have a feeling of the layout of the
experiment and a quick comparison of the plots.
I believe that lattice would be the right tool, but when I tried to
implement i got an error. Specifically the output would be a A4 pdf,
so with about 600 cm2 of drawing space, which gives about 1.5 cm2 for
each plot; removing the labels that might just work.
So I have the y values = 'fluorescence', x 'values' = cycles and 384
'well' data. I implemented to begin with:
xyplot(fluorescence ~ cycles | well,
ylab=Fluorescence,
xlab=Cycles,
main=list(draw = FALSE),
scales = list(
x = list(draw = FALSE),
y = list(draw = FALSE),
relation=same,
alternating=TRUE),
layout = c(24,16),
par.settings = list(strip.background=list(col=white)),
pch = .
)
but the the individual graphs show only the writing data instead of
the actual plots.
How can I overcome this error?
Thank you
Best regards
Luigi

Re: [R] Metafor - rma.mv function - variance components

Hi all, I have a question about metafor and the rma.mv function.

In metaSEM you can fix for example the variance within studies (sigma^2.1) to zero to test whether there is a significant difference in fit between the models (and if so, then there is significant heterogeneity between the effect sizes within studies). I was wondering if this is also possible in metafor. If I fix sigma2 to zero, then both variances are fixed to zero. However, I want to fix only one variance to zero. I hope that someone can help me.

xyz - data.frame(municipio = c('Limeira'), mesincident = c('marco'),
trechoklmetros = c(3.00, -4.00, 30))

[R] Fwd: REngine hangs when called within java code
Dear All,
I fixed my issue.
String newargs1[] = {--no-save};
Rengine r1 = Rengine.getMainEngine();
if (r1 == null) {
r1 = new Rengine(newargs1, false, null);
}
i added/modified the above part when setting up the rengine.
Somehow, now it works.
may be that in the previous coding, one instance of rengine do not
really end.hence it hangs when it comes to another instance.
Many thanks.

Subject: REngine hangs when called within java code
To: r-help@r-project.org
Dear All,
I'm creating a project which uses both java and R.
I created the java class named MyClass and within that wrote two
separate methods (graphing1() and fitness()) to call the r scripts.
public void graphing1() throws IOException {
String newargs1[] = {--no-save};
Rengine r1 = new Rengine(newargs1, false, null);
r1.eval(source('test2.R'));
r1.end();
}
public void fitness() throws IOException {
String newargs1[] = {--no-save};
Rengine r3 = new Rengine(newargs1, false, null);
r3.eval(source('A.R'));
r3.eval(source('B.R'));
r3.end();
}
Both of the above methods are in java class MyClass.
From another class in the same project for which I created a gui, I
accessed the fitness() function and it worked fine. But when I try to
call the graphing1() function it did not work. (both were called
through the gui) The programme hangs at ;
Rengine r1 = new Rengine(newargs1, false, null);
without any notification. In both instances I called the function as follows:
1st instance:
MyClass test=new MyClass();
test.fitness() ;
2nd instance:
MyClass test1 = new MyClass();
test1.graphing1();
All the 3 scripts are coded to create png files. test2.R and A.R
scripts use the ROCR library and B.R do not use any. All the 3 files
end with dev.off() statement.
I have installed R 3.1.3. I’m using netbeans as the editor and working
in windows environment.
The 3 scripts work fine when executed in R environment. The issue
arises when it’s called from the java code.
I'm a student who is new to R and was struggling to solve this issue
for several weeks. Your help is greatly appreciated.
Thanks in advance.

Thanks in advcance,

If I understand the message correctly, it is saying that the RODBC package
is not found, just as you said in the subject. That either means that you
have not installed it, or it is not on the library path. Perhaps the
simplest thing to try is to reinstall the RODBC package with the R
statement:
install.packages('RODBC')
then try again. If you need more help, you might want to post the output
from the commands: Sys.info() and .libPaths() and the value of the .Library

[R] Predict in glmnet for cox family
Dear All, I am in some difficulty with predicting 'expected time of survival' for each observation for a glmnet cox family with LASSO. I have two dataset 5 * 450 (obs * Var) and 8000 * 450 (obs * var), I considered first one as train and second one as test. I got the predict output and I am bit lost here, pre - predict(fit,type=response, newx =selectedVar[1:20,]) s0 1 0.9454985 2 0.6684135 3 0.5941740 4 0.5241938 5 0.5376783 This is the output I am getting - I understood with type response gives the fitted relative-risk for cox family. I would like to know how I can convert it or change the fitted relative-risk to 'expected time of survival' ? Any help would be great, thanks for all your time and effort.

[R] list server problem?
Dear all, I use Thunderbird 31.6.0 on Mac OS 10.6.8 to download my e-mails. Since this morning, Thunderbird downloads several times the same e-mails from the list, some even being from yesterday. It occurs only with e-mails from the R-help and not with my other professional and private e-mails. I also checked that it was not a problem with the server on which I get e-mails from the R-help: the problematic e-mails are erased every time from the server but are received several times. So I would say that the R-help server has sent these e-mails several times. I am wondering if there is currently an issue with the R-help server. Is someone else having the same problem? Thanks!

Re: [R-es] Como leer una BD con una estructura inadecuada
Estimado Eric ¿Cuál es el que necesita? Mire la página que usted dice, pero los archivos no son de 70 mb o 180 mb. Hay otras opciones pero se me ocurrió pasarlo a mysql o sqlite y enviarle los datos en sql. Aunque si logra usar xml, o como leí utilizando más especificaciónes con read.fwf el inconveniente se solucionaría. Aunque puede haber un problema, y es con la memoria, al respecto podría procesar de la forma que más fácil le resulte, pero por partes (archivos) y guardar el resultado del data.frame en el disco, borrar la memoria de R, procesar la siguiente parte, y luego unir todos los archivos que guardo en el disco. Si tiene inconvenientes, yo no tendía problemas en pasar todo a sql y usted luego lo importa.

In '?rep' find out about the 'each' argument.
Also there is the function 'gl' which creates a factor and offers a shorter

If n equals 5 use one of:

[R] R code/package for calculation of Wasserstein distance between two densities
Dear friends, Before reinventing the wheel, I was wondering if anyone can point me to code for calculating the Wasserstein distance between two densities. I am particularly interested in mixture densities (in functional form). I know that we have the earthmovers distance in R via the emdist package but it appears to me upon a quick look that this can not handle densities in functional form. So, I was wondering if anyone had any ideas on code for this problem. Many thanks and best wishes, Ranjan Can't remember your password? Do you need a strong and secure password? Use Password manager!

I am trying to generate a list of length 4n which consists of the
integers 1 to n repeated in groups of four, i.e.
1,1,1,1, 2,2,2,2, 3,3,3,3, . . . . , n,n,n,n
(The spaces in the list are added only for clarity.)
I can generate the list as follows, but the code must be modified for
any value n, and the code is UGLY!
c(rep(1,4), rep(2,4), rep(3,4), . . . ,c(n,4))
Can anyone help me?
Thank you,

Hi arnaud,
At a guess, it is the two hyphens that are present in those strings. I
think that the function you are using interprets them as subtraction
operators and since the string following the hyphen would produce NA,
the result would be NA.
I was thinking of 'x' as being the culprit (interpreted as multiply)
but you are right indeed
noHyphens - str_replace(playerStats[c(22,24)],'-','')
extract_numeric(noHyphens)

in fact:
-
extract_numeric

Is there any particular reason for the hyphen in gsub() ? Why not
remove it thus ?

The error is not from tapply(), it is from interaction.plot(). You
cannot supply a dataframe to this function, you must supply the three
arguments x.factor, trace.factor and response.
You could do:
by(ipd[,c(time,subjects,values)],ipd[,group],
function(x){names(x) - c(x.factor,trace.factor,
response);
do.call(interaction.plot,x)})
There are several other ways of organizing the syntax, but somehow you
have to make the arguments to interaction.plot() explicit.
I was somewhat surprised to find that do.call() does not work with
positional matching of arguments. I.e.
by(ipd[,c(time,subjects,values)],ipd[,group],
function(x){do.call(interaction.plot,x)})
does *not* work. The names of x have to match the names of the
arguments to interaction.plot().
I'm sure this makes sense but I don't understand it.
cheers,
Rolf Turner

Hi,
You can use the apply group of functions
n-5
k-4
unlist(lapply(1:n,rep, each=k)) # For vector output:
sapply(1:n,rep, each=k) # For a matrix output
Hope this helps

[R] high density plots using lattice dotplot()
Dear all, I am trying to plot the results of a PCR experiments that involves 384 individual plots. Admittedly the space for the plots will be tiny, but I just nedd some icon to have a feeling of the layout of the experiment and a quick comparison of the plots. I believe that lattice would be the right tool, but when I tried to implement i got an error. Specifically the output would be a A4 pdf, so with about 600 cm2 of drawing space, which gives about 1.5 cm2 for each plot; removing the labels that might just work. So I have the y values = 'fluorescence', x 'values' = cycles and 384 'well' data. I implemented to begin with: xyplot(fluorescence ~ cycles | well, ylab=Fluorescence, xlab=Cycles, main=list(draw = FALSE), scales = list( x = list(draw = FALSE), y = list(draw = FALSE), relation=same, alternating=TRUE), layout = c(24,16), par.settings = list(strip.background=list(col=white)), pch = . ) but the the individual graphs show only the writing data instead of the actual plots. How can I overcome this error?

Pude importar el txt que adjuntaste sin problemas con una función del nuevo paquete de Hadley Wickham (readr). En este paquete ha incluido una función para leer datos read_table() que mejora las prestaciones del read.table() que R trae por defecto. Una de las mejoras, además de la velocidad es que dado un conjunto de datos tabular a importar, la función primero lee el fichero línea a línea y hace una interpretación del contenido para luego ya importarlo con las columnas adecuadas. Esta función de esta manera simplifica mucho la forma de carga de un fichero comparándola con el read.table() que precisaba de múltiples parámetros para si uno quería ajustar las columnas a cargar y la velocidad.

Es decir, si un dato corresponde a la ultima columna y todas las anteriores estan vacias, al final de la sustitucion quedara asociado a la primera columna.

Re: [R] misbehavior with extract_numeric() from tidyr
Hi arnaud, At a guess, it is the two hyphens that are present in those strings. I think that the function you are using interprets them as subtraction operators and since the string following the hyphen would produce NA, the result would be NA.

Re: [R] Smart detection of wrap width?
At this point, and since we are in an X windows context, I think it might be easier to use the window manager's features and write a little macro or something that will send my setwid() command to the active window, then assign it to a simple keystroke. Then: resize the window; hit the keystroke, and you're done. True, it's not fully automatic, but it would be pretty quick and easy. Either that or give ESS a try, using the bit that Ista offered. Or maybe Rstudio? Peter's got a good start, but I too would be stymied at the last step; definitely beyond my skill. -Don -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 4/18/15, 1:41 PM, Peter Crowther peter.crowt...@melandra.com wrote: On Apr 17, 2015 7:37 PM, Paul Domaskis paul.domas...@gmail.com wrote: I don't suppose there is a way to have it automatically invoked when the window size/positition changes? Possibly, though it would take a little building. If you were to launch R directly when you start the xterm (loosely xterm R rather than the default) then R would receive a SIGWINCH signal whenever the xterm window size changes (xterm automatically sends this to its child process). R doesn't directly enable handling of the signal, but there's nothing to stop you loading a dynamic library with a little C code that set up a handler for SIGWINCH and, when it got one, ran the equivalent of the stty command to get the new width. The thing I've not been able to figure out is how the C code would ever then hand that to R asynchronously. Anyone?

Re: [R] Smart detection of wrap width?
I'm glad it's helpful!
Defining it and then invoking it in ~/.Rprofile would work, but then you
will need to be careful about managing both ./.Rprofile and ~/.Rprofile
files. If you have one of the former, then the latter does not get sourced
at startup (see ?Startup). Of course, you can put source('~/.Rprofile') in
a local ./.Rprofile to take care of that if you want.
But in the long run, it would be a better practice to put personal helper
functions like this in a package and then load it in your .Rprofile
file(s). Most of my ./.Rprofile files have
require(rmacq)
setwid()
in them (along with whatever other directory-specific startup actions I
want). The more personal helper functions you have, the more valuable it
will be to put them in a package instead of defining them in ~/.Rprofile.

Your function works exactly as I wished. I'll probably get smarter
with time (I hope) but would it be reasonably good practice to stick
this into ~/.Rprofile? I don't suppose there is a way to have it
automatically invoked when the window size/positition changes? (It's
still priceless even without automatic triggering).

A lot of this depends on what context you are running R in, e.g.,
Windows console, Mac console, or command line in a unix-alike. Or

capabilities provided by the operating system.
Have you yet encountered
options()$width
?
For example,
options(width=100)
will cause wrapping at 100, at least for certain kinds of output.
In an xterm shell running in an X windows context, I frequently use
setwid - function ()
{
if (!interactive())
return(invisible(NULL))
scon - pipe(stty -a)
stty - scan(scon, what = , sep = ;, quiet = T)
close(scon)
cstr - stty[grep(columns, stty)]
options(width = as.numeric(gsub([^0-9], , cstr, ignore.case =
T)))
paste(width =, options()$width, \n)
}
A function I wrote that resets the width option to match the window
widths, and therefore adjusts the wrapping after I resize a windwo.

[R] color handling in `barplot' inconsistent betwen `beside=FALSE' and `beside=TRUE'
hi,
consider the following example:
8-
x - matrix(1:6, 3, 2)
layout(1:2)
barplot(x, beside = TRUE, col = 1:6)
barplot(x, beside = FALSE, col = 1:6)
8-
it seems, it is not possible to make `beside=FAlSE' plots behave the same
as `beside=TRUE' plots (i.e. use unique colors for all bars or bar
components), or is it? if I do not miss something, I would say the present
behaviour (as of 3.1.3) is not (or not always, anyway) desirable. rather,
`beside=FALSE' should use the same color for all bars or bar components as
`beside=TRUE'.
any opionions on that?
in case someone needs this, the following patch achieves what I would
expect from `barplot(beside=FALSE, ...)' -- at least w.r.t. colors, if not
shading ... -- in the first place:

gsub('[^[:alpha:]]','',str1)==gsub('[^[:alpha:]]','',str2)
[1] TRUE
The gsub() removes all characters which are not alphabetic from each string
and then compares them.

Re: [R] Need online version of R help pages
Acknowledged, Michael. I appreciate the pointer to the info. For at least a short while, however, this is my only access to R, so I am using this environment to ramp up on times series and R as much a possible. I think it should suffice for that purpose, and the real analysis can occur in a more reliable installation R. I've managed to work the ropes on a better installation, but the solution won't be immediate.

Hello!
Please point me in the right direction.
I need to match 2 strings, but focusing ONLY on characters, ignoring

For example:
I want the following to return: TRUE
What a nice day today! - Story of happiness: Part 2. ==
What a nice day today: Story of happiness (Part 2)
I would transform both strings using gsub(), then compare.
e.g.
clean - function(s)
gsub([[:punct:][:blank:]], , s)
clean(What a nice day today! - Story of happiness: Part 2.) ==
clean(What a nice day today: Story of happiness (Part 2))
This completely ignores spaces; you might want something more
sophisticated if you consider today and to day to be different, e.g.
clean - function(s) {
s - gsub([[:punct:]], , s)
gsub([[:blank:]]+, , s)
}
which converts multiple blanks into single spaces.

Re: [R] list server problem?
Dear all, I use Thunderbird 31.6.0 on Mac OS 10.6.8 to download my e-mails. Since this morning, Thunderbird downloads several times the same e-mails from the list, some even being from yesterday. It occurs only with e-mails from the R-help and not with my other professional and private e-mails. I also checked that it was not a problem with the server on which I get e-mails from the R-help: the problematic e-mails are erased every time from the server but are received several times. So I would say that the R-help server has sent these e-mails several times. I am wondering if there is currently an issue with the R-help server. Is someone else having the same problem? Not having the same problem, but an explanation from the place where the server runs: The R mailing list server indeed has had hard times, as it seems since early Sunday (CEST), and a complete time out for a few hours during this morning. The symptoms have been that some e-mails were badly delayed and --- as you have experienced --- mail server timeouts do lead to e-mail being sent more than once. This is the consequence of a safe e-mail server behavior: If an e-mail may have been lost, rather send it again. As some say: Better error on the safe side. Martin Maechler ETH Zurich Thanks!

Hi Dimitri, str_replace_all is not in the base libraries, you could use 'gsub' as well, for example: a = What a nice day today! - Story of happiness: Part 2. b = What a nice day today: Story of happiness (Part 2) sa = gsub([^A-Za-z0-9], , a) sb = gsub([^A-Za-z0-9], , b) a==b # [1] FALSE sa==sb # [1] TRUE Take care of the extra space in a after the '-', so also replace spaces...

You can use the [:alnum:] regex class with gsub. str1 - What a nice day today! - Story of happiness: Part 2. str2 - What a nice day today: Story of happiness (Part 2) gsub([^[:alnum:]], , str1) == gsub([^[:alnum:]], , str2) [1] TRUE The same can be done with the stringr package if you really are partial to it. library(stringr) On Mon, Apr 20, 2015 at 9:10 AM, Sven E.

Re: [R] Smart detection of wrap width?
Paul Domaskis paul.domaskis at gmail.com writes: Yes, I found the width option in the help pages, but I was wondering if there was automatic setting of the wrapping according to the current window width. Your function works exactly as I wished. I'll probably get smarter with time (I hope) but would it be reasonably good practice to stick this into ~/.Rprofile? I don't suppose there is a way to have it automatically invoked when the window size/positition changes? (It's still priceless even without automatic triggering).

If you were to launch R directly when you start the xterm (loosely xterm R rather than the default) then R would receive a SIGWINCH signal whenever the xterm window size changes (xterm automatically sends this to its child process). R doesn't directly enable handling of the signal, but there's nothing to stop you loading a dynamic library with a little C code that set up a handler for SIGWINCH and, when it got one, ran the equivalent of the stty command to get the new width. The thing I've not been able to figure out is how the C code would ever then hand that to R asynchronously. Anyone? MacQueen, Don macqueen1 at llnl.gov writes: At this point, and since we are in an X windows context, I think it might be easier to use the window manager's features and write a little macro or something that will send my setwid() command to the active window, then assign it to a simple keystroke. Then: resize the window; hit the keystroke, and you're done. True, it's not fully automatic, but it would be pretty quick and easy. Either that or give ESS a try, using the bit that Ista offered. Or maybe Rstudio? Peter's got a good start, but I too would be stymied at the last step; definitely beyond my skill.

Hi,
You can go the other way:
layout(1:2)
barplot(x, beside = FALSE, col = 1:3)
barplot(x, beside = TRUE, col = rep(1:3, 2))
You could use the following workaround:
barplot(cbind(1:3, c(NA, NA, NA)), beside = FALSE, col = 1:3, ylim = c(0, 15))
barplot(cbind(c(NA, NA, NA), 4:6), beside = FALSE, col = 4:6, add = TRUE)
That essentially plots each stack separately, using the respective NA columns
to space the two stacks in the plot. In the first call, also setting the y axis
limits to handle both stacks. In the second call, using ‘add = TRUE’ so that
the second plot does not overwrite the first.
The use of stacked bar plots is typical when trying to visually compare the
same categories across groupings, thus the same colors in each stack by
default. This is not always easy if the differences are subtle, similar to the
issues with pie charts.
I would not advocate changing the current behavior, as a lot of long standing
code would break, including functions in packages that are built on top of
barplot() and expect certain default behaviors.
You can always make a local modification of barplot() for your own use and/or
consider that there might be a logical CRAN package for graphics extensions
where it could be included as an add-on function.

Hi,

thanks for responding.

layout(1:2)
barplot(x, beside = FALSE, col = 1:3)

well, that would make it consistent but it is not what I want, actually

yes, I see. that indeed would work. however, in my actual use case, I have
a looong time series with dozens of bars. so it would become quite ugly
(looping over all the bars subsetting the color vector etc). but yes, one
could do it this way.
The use of stacked bar plots is typical when trying to visually compare
the same categories across groupings, thus the same colors in each stack
by default. This is not always easy if the differences are subtle,
similar to the issues with pie charts.
I would not advocate changing the current behavior, as a lot of long
standing code would break, including functions in packages that are
built on top of barplot() and expect certain default behaviors.
yes, I was expecting this answer and I understand it, of course. on the
other hand, it would be rather straightforward to add another argument to
`barplot' to control the behaviour (while defaulting to the present one).
I would think this would be a good addition: in my use case, e.g. I do
have such categorized and grouped data and just want to be able to plot
them after sorting within each group according to value while maintaining
unique color assignments independent of whether the data are sorted within
each group or not. and with `beside=FALSE' this is completely
straightforward (just resort the color vector together with the data),
while it fails with `beside=TRUE'.
You can always make a local modification of barplot() for your own use
yes, that's what I did. but I wonder how many people would benefit from
the ability of easily plotting the same data with the same color vs. data
correspondence independent of the `beside' setting. but it's for the devs
to decide...

I wish the post quoted below had made it to the mailing list, as I could have saved you the trouble of trying to seek a solution on my behalf. I'm quite happy using vim and in fact consider it to be my right hand (even though I don't dive under the hood much). So this post was really about getting around the broken cygwin help facility for R rather than editing. Also, at work, we have to keep the work on-site. For those unfortunate enough to have no option but to use cygwin's R, here is the posting re. a workaround to the broken help facility, posted via nabble (which probably explains why it didn't make it to the mailing list): Sent: April-16-15 5:51 PM Subject: Re: Need online version of R help pages I was able to get the help info for many of the commands from the link for The R Reference Index at http://cran.r-project.org/manuals.html. However, I found that I could also get help from the R prompt via help(myHelpTopic,help_type=html) To make that work, I needed options(browser=cygstart) in ~/.Rprofile. Very puzzling to a non-web-developer like myself: The URL for the help content is (for example) http://127.0.0.1:16086/library/stats/html/reshape.html. This is a loop-back address. I did *not* see any file named reshape.html in subdirectory library/stats/html/reshape.html when I went to R.home(). I thought that perhaps the file was being composed on the fly. However, I was under the distinct impression that my account did not have the ability to set up servers (and I assume that the page that is composed on the fly must be served out by a server). __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

[R-es] Como leer una BD con una estructura inadecuada
Hola Eric.Le detallo que es lo que yo hago en estos casos.Identificar el tipo de archivo, es decir, que separadores de columnas tiene ?, que tipo de datos debe tener cada variable?, etc.Si el archivo es muy grande y un editor de texto (como Note++) no lo puede abrir por temas de memoria, puede usar un programa adecuado para esto. Yo uso glogg (http://glogg.bonnefon.org/) que me ha permitido abrir archivos de texto de hasta 3 GbSi no tiene delimitadores, puede usar la opci�n de carga, campos de ancho fijo, en donde usted debe dar las longitudes de las variables.Si no puede identificar claramente los tipos de datos o los valores por defecto, cargue la variable como character, para que luego con las funciones adecuadas, pueda transformarla y obtener los tipo de valor y variables deseados.Con respecto a los espacios, c�rgelos como le explique, y luego transforme a la variable reemplazando los mismos con la funcion grepl y si es mas complicado con una expresi�n regular.Los paquetes que le pueden ser de ayuda: data.table (funcion fread), readr, stringr.Espero le sirva.Saludos. --Archivo adjunto de mensaje reenviado-- From: c...@qualityexcellence.es CC: r-help-es@r-project.org To: ericconchamu...@gmail.com Date: Mon, 20 Apr 2015 11:42:03 +0200 Subject: Re: [R-es] Como leer una BD con una estructura inadecuada El 18 de abril de 2015, 20:03, eric ericconchamu...@gmail.com mailto:ericconchamu...@gmail.com escribi�: Estimados, tengo el siguiente problema: Tengo una BD de 19 columnas y aprox 500 mil filas, la que tiene muchas celdas vacias y esta separada con espacios para hacer coincidir los datos bajo los encabezados.

Re: [R] feature selection
Although I am sure many here would be happy to help you your question is far too vague. There are many methods for feature selection. You should review the literature and see what would work best for you or consult a statistician. Once you have selected a method and began an initial attempt at the R code then this list will be far more helpful to you. This help list is meant to help people with their R programming not design their analysis for them. Some places to start with R include the very popular 'caret' package. Max Kuhn (the author) has a wonderful website with many tutorials. Here is the front page for feature selection, http://topepo.github.io/caret/featureselection.html I also have developed a package on Bioconductor called 'OmicsMarkeR' which you can find at http://bioconductor.org/packages/release/bioc/html/OmicsMarkeR.html that you may find useful depending upon the data you possess.
