[R] package precedence question
Dear R help I am writing a package where I am intending to extend the png function of the grDevices package. When I load my package, my png function indeed substitutes the grDevices function, and everything seems OK. I am a little confused though at how function precedence is determined. I am concerned that when the package moves into production on a webserver that instances may occur when the precedence breaks and the grDevices function becomes the version. I wish to avoid the need for the explicit calling of the myPackage:::png function, is there a way to encourage or coerce the precedence with which packages are loaded and in which functions are evaluated. Some pointers as to where I might find the solution (or a more appropriate nomenclature) would be very gratefully received.

Hi everyone!
May I request again for your help?
I need to make some codes using if else statements...
Can I do an if-else statement inside an if-else statement? Is this the
correct form of writing it?
Thank you.=)
Example:
for (v in 1:6) {
for (i in 2:200) {
if (v==1)
(if max(x*v-y*v)1 break())
if (v==2)
(if max(x*v-y*v)1.8 break())
if (v==3)
(if max(x*v-y*v)2 break())

[R] printing text within if functions inside a for loop
Hi
I am having a problem with outputting text inside an if function. I have the
following code:
for (j in 20:length(bb.up))
{
if (up[j]==1 up[j-1]==0)
{
sprintf(Long on %s at a price of %f,dates[j],data[j])
}
if (down[j]==1 down[j-1]==0)
{
sprintf(Short on %s at a price of %f,dates[j],data[j])
}
}
The loop runs fine and the sprintf function runs fine on its own, but the
problem I am having is that there is no output if I run the loop with the
sprintf inside it. Does anyone know what could be wrong? Is there a way for
the code to output data within this loop? I can't seem to find anything on
the internet for this problem.
Thanks in advance.

[R] Log linear model - Showing non-deviation form in glm()
Hey, Whenever I set up a log linear model using glm(Y~. , data=data, family=poisson) I get the parameters in the form of deviation from the first cell kombination. I find this to be hard to interpret when I for instance want to know if there is a difference between two factors in the first category since those parameters are not shown directly. Is there any way to get the summary() command, or equivalent, to show me all of the parameters in the model in non-deviation form? I can use loglin() to get the parameters, but it doesnt show significance of the parameters from what I can tell. Alternatively, can anyone give a brief explanation of how to interpret the model in deviation form? For example here I have the factors Gamla and Nya and the categories 0, 1-10, 11-50, 51-100 and 101+ The interpretation of the shown interaction terms are no problem, but how do I figure if there is a difference between Gamla and Nya when it comes to category 0?

Re: [R] Mosaic plots
As pointed out by others, vcd supports mosaic plots on top of the grid engine (which is extremely helpful for those of us who love playing around with grid). The standard mosaicplot() function is directly available (it isn't clear if you knew this). The proper display of names is a real challenge faced by all of us with these plots, so you should try each version. I'm not sure what you intend to do with a legend, but if you want the ability to customize and hack code, I suggest you look at grid and a modification to vcd's version to suit your purposes.

[R] rdcomclient issue - member not found when using borders
I wrote a procedure to create a spreadsheet using rdcomclient. It uses a
function to do the writing and runs correctly in isolation. It gives
errors, but it continues to completion. The error I receive is Error:
Member not found. If I place it inside a for loop the loop fails after
the first iteration, once it reaches the error.
Has anyone had experience with this error? Here is the code that is
causing the problem.
library(RDCOMClient)

The line that is causing the problem is :

HorizontalAligment properly (the code commented out).

Re: [R] R-installation regarding.
Hi Frederick, The development files for readline are not available. Install them to get this working. For debian/ubuntu the package to install is called libreadline-dev or something. SUSE's package manager might have a similar package. Alternatively you can skip installing R from source and use binary packages that are available in .dev, .rpm etc from CRAN [1]. This ensures you have the latest version of R and that upgrading is done through the package manager of SUSE, minimizing your work. cheers, Paul [1] http://cran.r-project.org/bin/linux/suse/ fredrick devadoss wrote: Hello All, I am new to R and tried to install R in Linux system (OS: Open SUSE).

Re: [R] If else statements
The short answer is yes, you can, but your syntax is wrong. You need
to make sure you wrap your conditions inside brackets, and use {, not
(, to delineate your if statements.
for (v in 1:6) {
for (i in 2:200) {
if (v==1){
if (max(x*v-y*v)1)
break()
}
}
}
et cetera

[R] Solutions for memory problems (packages ff, bigmemory)?
Hello, I want to impute missing values using the package mi. My file has around 28 MB (50.000 observations, 120 variables). My computer is a Windows XP 32-bit machine, 4 GB Duo Core processor. When I run mi, already after some minutes during iteration 1, I get the message that a vector allocation fails. Even with a 10% sample of the dataset, it doesn't work. I've read about the packages ff and bigmemory. Can they help me that the mi package doesn't use the RAM for temporary files but the hard drive instead? Since I'm not a R expert, I don't understand completely how these packages work. Or are there other packages for a better memory management? Or is really a 64-bit OS the only solution for this problem? I hope that there are some suggestions for my problem since many R procedures seem to be very promising but they don't work on my machine because of the memory limitation.

[R] multi-stage sampling and hierarchical models: which packages?
Dear wizaRds, I have a dataset to analyse which is causing me problems. It is a sample of parents in schools. First we had a population table of the schools in the country in question divided into five regions, and in each region we have an urban/rural split. The population Ns in these ten cells are known. Then three schools were drawn from each cell according to the Lahirie method, i.e with probability of being selected depending on school size. Students were then drawn randomly from the schools, again with probability proportional to school size. Details of this are below in case this is important. I have calculated the weights. So I have a weighting problem and a mixed levels problem at the same time. Even if I just use the survey package I am not sure how to specify the model, because I have clusters within strata rather than strata within clusters. I guess it would look something like dstrat-svydesign(id=~schoolC,strata=~region+urbanrural, weights=~newweight, data=mydataset,nest=T), but this gives the same results as dstrat-svydesign(id=~schoolC,strata=~region, weights=~newweight, data=mydataset,nest=T) And I can't see any way to look at the mixed levels effects using that package. Perhaps I am better advised to use nlme; I guess I can just use the weights as a covariate? My ultimate aims are to conduct various regressions in which I expect the school- and region-level effects to be strong. Ideally I would like to use sem as well, but then I am really stuck. If someone could put me on the right track I could be more specific with reproducible examples etc Best Wishes Steve Powell **details of Lahirie method as we used it: the schools were put into a list in order of ascending size (student population) and this list was divided into three bands containing 25%, 35% and 40% of all the students in the cell, respectively; and three schools were chosen randomly from each size band. Then samples of students were drawn randomly from lists of students at each school, so that more students were chosen from the larger schools: 20, 30 and 40 from each of the smaller, medium and large schools. So we have (20+30+40)*3 students per cell, for 10 cells = 2700 students in this country. www.promente.org | skype stevepowell99 | Thailand +66 8 4438 2667 [[alternative HTML version deleted]] __ R-help@r-project.org mailing list 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] glmpath and coxpath variables
Hi, I am analyzing a set of variables in order to create a survival model for a set of patients. I have checked the reference manual for glm path and coxpath in order to achieve it. However I have a doubt about the class of the covariates I can use with the last mentioned package. In the example, the package loads a list called lung.data. This object has a matrix with the covariate information x and two vectors about the censoring and the time to the event. The information in the x matrix seems to be numeric, but some of the covariates could be categorical (1st and 2nd columns) because they only have 2 or 4 different values. If we check their class they are numeric. Thus, the question is: can I use categorical and continuous covariates in this matrix (x)? Thanks a lot, Antoni.

Re: [R] using a list to index elements of a list
Thanks for your reply Ben!
I don't think I want v to be identical to x... I guess I haven't put the
question in the right context. What I'm actually trying to do is... (*
indicates extra information, not necessarily relevant for my question, but
to help put it in context)
A, some matrix (*a traceless, symmetric matrix of 0's, 1's (representing a
graph)*)
x-list()
x[[1]]-1:nrow(A)
for (i in x[[1]]){
if (A[1,i]==1) {
x[[2]]-x[[1]][!(x[[1]]==1)]
for (j in x[[2]]){
if (A[i,j]==1){
path-c(1,i,j)
print(path)
}
}
}
}
So, here I have used i and j to range over the elements of x[[1]], x[[2]]
respectively.
(*This prints all the paths of length 2 starting at vertex 1. But I'm trying
to generalise this for a path of length nrow(A), i.e. a Hamiltonian path)*)
I want to iterate this process a certain number of times, so instead of i,j
I thought to use a list of scalars, v.
I don't want v to be identical to x... I want v to be a list of scalars
which range (inside a for loop) over an elements of the list x. (so instead
of for (i in x[[k]]) I have for (v[[k]] in x[[k]])).
I can see how they look similar, but I do think they're different objects.
Hope this is clear. If you still think using 'x' itself would work, can you
explain how so?

[R] Sample size for proportion, not binomial
Hello, I am looking for a sample size function for samples sizes, to test proportions that are not binomial proportions. The proportions represent a ratio of (final measure) / (baseline measure) on the same experimental unit. Searches using RSeek and such bring multiple hits for binomial proportions, but that doesn't seem to fit my situation. Perhaps there's some standard terminology from a different field that would provide better hits than deeming this a 'rate' or a 'proportion'. Of course, most sample size functions assume a normal distribution, while this data will be bounded between 0 and 1. The scientist I'm working with feels it's important to make fair comparisons, any weight loss must account for the baseline weight. A logistic transformation seems appropriate, but that term also didn't yield hits I recognized as useful.

Re: [R] using a list to index elements of a list
and in addition to bill's suggestion, you may want to consider not
growing a list.
Instead of 'v - list()', use:
v - vector(list, nrow(A))
b
Will your code work as you wish if you
replace the for(v[[1]] in x[[1]]) { ... }
with the following?
for(i in x[[1]]) {
v[[2]] - i
...
}

Re: [R] filled.contour formatting questions
Hmm yes that is what I'm looking for in terms of color scale control, but I
need it for contoured plots. John.

Hello, I'm having some trouble getting things to look as I want with
filled.contour.
1. My first issue is that I am unable to add line segments to my plot
where
I want them. Using the rug pattern example:
x- y- seq(-4*pi, 4*pi, len = 27);
r- sqrt(outer(x^2, y^2, +));
filled.contour(cos(r^2)*exp(-r/(2*pi)));
segments(0.2,0.2,1,0.2);
The line segment is not found in relation to the x-axis but is seemingly
squished over by the color bar.
If I try to achieve the line this way:
filled.contour(cos(r^2)*exp(-r/(2*pi)),plot.axes={lines(c(0.2,1),c(0.2,0.2))})
Now when I add the axis back it is misaligned.
axis(1).
2. Secondly I'm finding the literature difficult to understand on how to
make a nice color scheme. Below is a nice scheme I found from an example,
except I don't understand why the scale seems to cycle into blue again for
larger values, even though I think I am setting the number of levels of
colors and contour levels to be equal. Basically I want reds for the
highest values and blues for the lowest:
filled.contour(cos(r^2)*exp(-r/(2*pi)),nlevels=25,col=hsv(h=seq(from=.7,to=0,length=25)))
3. I'm used to working with matlab where it was simple to make the color
scale the same on multiple figures using caxis(). However I don't see
this
option for filled.contour (possibly it exists for levelplot() but I was
having even less success understanding that one). I only see the option
to
set the number of levels which doesn't really accomplish what I want for
plots that are going to have widely varying limits.
Hi John,
I'm not sure that this is what you want, but the examples for the barp
function in the plotrix package include one for a color scale that extends
beyond the values that are to be plotted. That is, you can specify the range
of the color scale regardless of the actual values.

[R] Operator overloading for custom classes
Hi, I need some help to get some of the object orientation, specifically the methods that overload the basic arithmetic operations, from sample C++ code to R. I don't have experience with such advanced language features inside of R. So I was wondering if some of you could help me out in this regard. I have written a simple demonstration of a forward mode automatic differentiator in C++ and it is currently hosted on github: http://github.com/quantumelixir/ad-demo/blob/master/simple.cpp. It uses simple operator overloading techniques to modify the meaning of the basic arithmetic operations (+, -, *, /) for the derivative type Dual number class that I have defined. Could you show me how this could be equivalently done in R? I want to know how to define custom classes and define the meaning of arithmetic for them. I had checked for operator overloading in R but could only find the equivalence of a + b and '+'(a, b) in the R language definition. Could you show how I could extend the simple object oriented-ness in the C++ code neatly to R? Thanks a bunch!

Dear R-helpers,
I have a dataframe like this:

49 1 1 1 0 NA NA
50 1 1 1 1 NA 1
I would like to convert a missing value (NA) that follows a 0 (zero) or
another missing value (NA) into a 0 (zero).
So, the above lines would be converted to:
ID X1 X2 X3 X4 X5 X6
49 1 1 1 0 0 0
50 1 1 1 1 NA 1
I have been struggling with this all morning, so any help you could provide
would be much appreciated.
Thank you!

Re: [R] Creating pdfs using qplot in qqplot2

I am trying to create plots within a for loop and output them to a pdf.

plot(gg$datadate, gg$spread, main=i)

I am trying to learn more about ggplot2 so I try a slight modification
and it doesn't work. Anyone know how to do this using qplot in ggplot2?
gg - data.frame(datadate=1:4, spread=5:8)
pdf()
for (i in 1:3) {
qplot(gg$datadate, gg$spread, geom=line, main=i)
}
dev.off()
This question gets asked many, many times and is answered in FAQ 7.22:
http://cran.r-project.org/doc/FAQ/R-FAQ.html#Why-do-lattice_002ftrellis-graphics-not-work_003f
Basically, old-school functions like plot() execute plotting commands
directly when they are called. With Lattice-based graphics, like ggplot2,
the composition of the plot and the execution of the plotting commands are
separated into two steps. qplot() returns an object that contains the
composition of the plot, the print() method performs the actual execution of
plotting commands to a graphics device.
When functions are called interactively in the top-level environment, an
implicit call to print() is executed to display the results. When these
same functions are used inside another function or for() loop, you will need
to explicitly add the call to print() in order to get the same effect.
Hope this helps!

The proportions represent a ratio of (final measure) / (baseline measure) on the same experimental unit.

Perhaps there's some standard terminology from a different field that would provide better hits than deeming this a 'rate' or a 'proportion'. Of course, most sample size functions assume a normal distribution, while this data will be bounded between 0 and 1. The scientist I'm working with feels it's important to make fair comparisons, any weight loss must account for the baseline weight. A logistic transformation seems appropriate, but that term also didn't yield hits I recognized as useful. Loss of weight --- compare treatments: Treatment A: 1 - Final weight / Initial weight Treatment B: 1 - Final weight / Initial weight This appears to be a situation that would be common, but I'm not framing it in a way that matches an R package. Any guidance is appreciated. Regards, Paul If you and the scientist are in a position of being open to better options of analyzing change from baseline data, I would recommend that you both read the following two papers: Statistics notes: analysing controlled trials with baseline and follow up measurements. Vickers AJ, Altman DG. BMJ 2001;323:1123–4. http://www.bmj.com/cgi/content/full/323/7321/1123 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1121605/pdf/1123.pdf The use of percentage change from baseline as an outcome in a controlled trial is statistically inefficient: a simulation study. Vickers AJ. BMC Med Res Methodol 2001;1:6. http://www.biomedcentral.com/1471-2288/1/6 http://www.biomedcentral.com/content/pdf/1471-2288-1-6.pdf and review an additional web site: http://biostat.mc.vanderbilt.edu/wiki/Main/MeasureChange Once you are hopefully in a position of adopting a regression based approach (eg. FinalWeight ~ BaseWeight + Treatment), there are various options for calculating sample sizes. The key advantage of this approach is that you get the baseline adjusted between-group comparison (the regression beta coefficient and confidence intervals for Treatment) which is the key outcome of interest in comparing treatments in a parallel design. The easiest, albeit conservative approach for sample size, is to use power.t.test() on your assumptions of the inter-group delta for actual weight change (not percent change), the std dev for actual change, desired power and target alpha. I am not aware off-hand of any power/sample size functions in R for regular linear regression, though they may exist. There are third party programs that do provide that functionality. If you are willing to code and experiment a bit, you could construct a monte carlo simulation with a linear model, using data generated with rnorm() based upon reasonable assumptions about the distribution of your data in each group for the baseline and final values. Once you get your actual data collected and ready for analysis, you will also need to test for a baseline*treatment interaction (FinalWeight ~ BaseWeight * Treatment), which can make the interpretation of treatment effects more complicated, since the treatment effect will be conditional upon the baseline weight, rather than being able to report a mean treatment effect.

Re: [R] Setting breaks to data more appropriately

[R] Bold greek letters using plotmath
I'm trying to annotate some graphics using plotmath and finding out that the
code I'm using isn't bolding the greek letters - it bolds the rest (once I
adjusted the numerics to characters), it's just failing on the greek
characters.
Any suggestions welcomed.
Jim Price.

Test code:
plot(1:5, type = 'n')
# The not bold version
text(2, 2:4, cex = 2, labels = do.call(expression,
unlist(list('Placebo', lapply(c(3, 6), function(.x) substitute(.x ~~ mu
* g
/ kg / hr, list(.x = .x, recur = F)))
# The bold version - note that the greek letter doesn't change
text(4, 2:4, cex = 2, labels = do.call(expression,
unlist(list(substitute(bold(Placebo)), lapply(as.character(c(3, 6)),
function(.x) substitute(bold(.x ~~ mu * g / kg / hr), list(.x = .x,
recur = F)))

[R] Diffusion entropy analysis
Hello, Does anyone know of an R implementation of diffusion entropy analysis (DEA) as proposed by Scafetta dn Grigolini (2002)? I was unable to find any existing functions, so I attempted to write up my own, but cannot reproduce known results, so obviously I'm doing something wrong. If there does not appear to be any existing script, I'll send along my attempts for your critique. I'd also be happy for any leads on scripts written in languages other than R.

[R] Plot ``freezes''.
In an elderly version of ``plotSymbols'' (now in the cwhmisc package) that
I had lying around, there was the example
plot(1:10,xlab=\374)
which the comments said would give a u-umlaut as the x-axis label.
When I execute this plot
(a) I get no x-axis label at all, and
(b) the plot ``freezes'' in that further plotting commands
(e.g. plot(runif(42))) produce no results. The plot window (X11)
remains as it was after the ``plot(1:10,xlab=\374)'' command.
No error message is given, but no new plot is produced.
If I do dev.off(), then normal plotting recommences. Can anyone explain
to me what is going on here? My session info is given below. I run R
from the command line, from a terminal window.
cheers,
Rolf Turner
