[R] Math elements in panel headers of lattice plots?
Hi, I would like to put a math expression in the header of a panel. Acctually, I need to substitute the 'a' to a script-a in a transcription contained in the factor by which the data set is divided. So, /spak/ should be /spAk/ where A should be a script-a. I guessed that math expressions would be the way to go on this.. Is this possible? /Fredrik -- Give up learning, and put an end to your troubles. __ R-help@stat.math.ethz.ch 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] Two sets of axis in a lattice plot?
Dear list, Is it possible to have lattice provide two different ordinate axis, one on the right side and one of the left side of the plot? I would like to make a xyplot with x both in a linear scale and in a log-approximate scale.

[R] Increase the number of plotting characters in dotplot (lattice)?
Dear list, I am using the dotplot function of lattice and like it very much. However, in some of the plots, I have more than 7 categories that I would like to represent by different plotting characters in the graph, which is a problem. For the categories after the 7th, the plotting characters are recycled, creating a confisuing graph indeed. So, my question is: how do I increase the number of unique plotting characters? /Fredrik __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
Re: [R] forcing apply() to return data frame
Hi, There is a frameApply fynction in the library gdata from the gregmisc package. The manual says it is like the function 'by', but returns a data.frame. Maybe this is something for you? /Fredrik 2006/4/21, Federico Calboli [EMAIL PROTECTED]: Hi All, I am (almost) successfully using apply() to apply a function recursively on a data matrix. The function is question is as.genotype() from the library 'genetics' apply(subset(chr1, names$breed == 'lab'),2,as.genotype,sep =) Unfortuantely apply puts it's results into a matrix object rather than a data frame, tranforming my factors into numerics and making the results useless.

Re: [R] prop.table on three-way table?
Hi marc, I did not manage ctab to do this for me. Again, I am probably using it wrong, but I don't know that the problem is. You asked for a more illustrated example, so here goes: Take this table: ftable(table(sample(paste(dim1_no,1:5,sep=),10,replace=TRUE), sample(paste(dim2_no,1:5,sep=),10,replace=TRUE), sample(paste(dim3_no,1:5,sep=),10,replace=TRUE))) dim3_no1 dim3_no2 dim3_no3 dim3_no5 dim1_no1 dim2_no1 0000 dim2_no2 0020 dim2_no3 0000 dim2_no4 0000 dim2_no5 0000 dim1_no2 dim2_no1 0000 dim2_no2 0000 dim2_no3 0000 dim2_no4 0000 dim2_no5 0101 dim1_no3 dim2_no1 0000 dim2_no2 0000 dim2_no3 0010 dim2_no4 0000 dim2_no5 0000 dim1_no4 dim2_no1 1000 dim2_no2 0000 dim2_no3 0000 dim2_no4 0000 dim2_no5 1000 dim1_no5 dim2_no1 0000 dim2_no2 0100 dim2_no3 1000 dim2_no4 0100 dim2_no5 0000 Now, I would like to get the per cent occurrence of each level of dim3_noX witin the cells by dim1 and dim2. Thus, for this part section of the table above: dim3_no1 dim3_no2 dim3_no3 dim3_no5 dim1_no2 dim2_no1 0000 dim2_no2 0000 dim2_no3 0000 dim2_no4 0000 dim2_no5 0101 I would like to get: dim3_no1 dim3_no2 dim3_no3 dim3_no5 dim1_no2 dim2_no1 0000 dim2_no2 0000 dim2_no3 0000 dim2_no4 0000 dim2_no5 00.500.5 since dim3_no2 represented 50% of the frequency within the cell created by dim1_no2 and dim2_no5.

[R] Extra \input command in Sweave created figures.
Dear list,
I am using Sweave to generate figures and tables for my thesis. Now, I
have run into the problem that all of a sudden, Sweave produces not
only an \includegraphics command, but a
\include command as well. This breakes LaTeX processing.
This is an example:
The code:
\begin{figure}[htbp]
\centering
mannerSimpleSkal,fig=T,height=5=
sel - mannerDF$target %in% c(skal,kal,sal,gal)
mannerDF$onsetLength == 1
print(
dotplot(
prop.table(table(mannerDF$agem[sel],mannerDF$target[sel],mannerDF$manner[sel]),1)
,auto.key=list(
space=right
)
)
)
@
\caption[Relative frequence of occurence for each manner of
articulation in simple productions of Skal,kal,gal and
sal]{Relative frequence of occurence for each manner of
articulation in simple productions of the skal,kal,gal and sal
target words.}
\label{fig:manner-skal-simple}
\end{figure}
Produces this LaTeX output when run through Sweave:
\begin{figure}[htbp]
\centering
\input{manner-mannerSimpleSkal}
\includegraphics{manner-mannerSimpleSkal}
\caption[Relative frequence of occurence for each manner of
articulation in simple productions of Skal,kal,gal and
sal]{Relative frequence of occurence for each manner of
articulation in simple productions of the skal,kal,gal and sal
target words.}
\label{fig:manner-skal-simple}
\end{figure}
What is causing the extra \input? I had this problem once before, but
was enable then to fix the problem by randomly adding and removing
blank space. Now, this problem seem to have occured in 18 figures,
which means I would like to find the acctual problem this time rather
than trying to remove the symptoms.
Thankful for all the help I could get.

[R] Convert ftable to latex?
Dear list,
I cannot make the latex command to output a ftable objet the way I
want it. Is it posible?
I found a post in the archives saying that one should use the rgroup
and n.rgroup arguments to supply the row names, but so far I have been
unsuccessful.
This is what I have:

As you can see, I do not get any row names, and I want two layers of
them (votcat and age in the formula). Column names work ok.
Please, help me recreate the table above in latex form (if it is
indeed possible).

Re: [R] Convert ftable to latex?
Thank you so much David.
That example provided me with enough information for me to convert the
table to latex, with
subdivisions intact.

Hi Fredrik,
What you need to do is to massage your table a little to get it into the
appropriate structure and then use the rgroup and n.rgroup options.
Here's an example using the Titanic data that come with R. Note that
this is not necessarily (or even remotely likely?) the best way to get
your data into the shape required, but hopefully it shows you what, in
general, you need to do. You might find that you don't need to use
ftable at all, you might find other ways of creating the table you need.
In the example below, note in particular what x and x2 look like.

Re: [R] Not loading libraries
Dear list, I'm sorry about not providing all the necessary details. The R call is: library(tools); Sweave(\$*.Rnw\) | R --no-save -q Using the --vanilla switch, I am able to keep the libraries from loading, but since I need some of the datasets in the .RData file, my call to Sweave fails. I have not been able to find loading of libraries in an ,Rprofile, and my options contains this: options(defaultPackages) $defaultPackages [1] datasets utils grDevices graphics stats methods Prof. Ripley is right when assuming that the libraries are loaded because of me trying out the Rcmdr GUI and then doing a save.image(). What I did not know was that I managed to save the loading of libraries at the same time.

Re: [R] Groups in histograms?
Dear list,
Sorry for answering my own post, but I have had partial sucess in
this. With the panel function below, I get separate histograms in each
panel using the group argument.
histogram(~vot | agem, nint=50,data=work,groups=Type, subset=agem 24
agem 30, panel=panel.grouphist,type=count,ylim=c(0,20),auto.key=T)
panel.grouphist - function(x,groups,...){
add - T
grouplevels - unique(groups)
ngroups - length(grouplevels)
for(i in 1:ngroups){
gcol - trellis.par.get(superpose.fill)$col[i]
gx - x[groups == grouplevels[i]]
panel.histogram(gx,col=gcol,...)
}
}
However, the color I get in the key using simpleKey is not the same as
the one in the the plot.
How do I get the two functions to use the same color scale?

What I need is the groups to be inside of a single panel, not in

Kind of like an histogram version of the xyplot(Y ~ X1,
groups=X2,panel=panel.superpose) command. (I hope this is correct).

However, I have not been able to find a way to do this. histogram does not seem to have a group argument. Please help. /Fredrik __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
Re: [R] Groups in histograms?
Hi Gary, I have found this, but it is not exactly what I am looking for. What I need is the groups to be inside of a single panel, not in different panels. Kind of like an histogram version of the xyplot(Y ~ X1, groups=X2,panel=panel.superpose) command. (I hope this is correct). /Fredrik On 8/8/05, Gary Collins [EMAIL PROTECTED] wrote: Have a look at the histogram function in the Lattice package. if x are your data to be displayed and y is your grouping variable you can just do histogram(~x|y) HTH Gary On 08/08/05, Fredrik Karlsson [EMAIL PROTECTED] wrote: Dear list, I would like to create histograms for up to three groups, with distincive colour/pattern, in a trellis panel.

[R] wapply from gplots -- How do I get a local estimate of variance?
Dear list, I am trying to plot the local variance in a moving window on a dataset. The function that I am trying to use for this is wapply from gtools. However, from the lattice panel function code: snip cat(x) cat(y) wapply(x,y,method=range,width=1/10,fun=sd,na.rm=TRUE) - outvar /snip I get: snip 109 109 109 109 109 109 116 116 116 116 119 119 123 123 123 123 127 127 133 133 133 133 133 138 138 138 138 138 138 138 138138 138 138 142 142 142 142 142 142 142 147 147 147 147 147 158 158 158 158 158 158 158 158 158 158 158 158 158 20.234 28.431 10.762 45.613 15.028 10.775 18.516 13.371 18.516 13.371 20.61 31.08 9.338 210.77 11.927 39.438 -35.079 15.872 12.272 9.1122.665 7.355 22.057 -49.289 11.212 16.236 20.654 16.236 20.654 15.181 57.271 37.513 57.271 37.513 8.518 -108.517 -14.444 10.702 4.482 16.422 23.003 42.451 12.998 42.451 12.998 14.292 5.945 7.115 16.079 -13.172 10.62 16.079 -13.172 10.62 16.079 -13.172 10.62 20.477 22.656 Error in var(x, na.rm = na.rm) : 'x' is empty /snip What am I doing wrong with this?

[R] Subset with selection variable from function argument. Is there another way?
Dear list, I'm making my current code more generic and would like some advise. The basic problem is subset and the name of the column to be compared for selection. What I've come up with is data(mammals) set - bottompremolars subset(mammals, eval(parse(file=,text=set)) 2) This seems a bit odd. Is there a nicer way? /Fredrik __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Re: [R] R and unix tool 'screen'
Hej Giampiero! Odd. Using Screen version 3.09.11 and R-1.8.0 on a Debian system, R does not trap C-a. I can fire up R in a screen, create a new screen with C-a c and even detach/reattach the screen session. The terminal emulator is xterm. Perhaps you are using a terminal that traps the C-a? (just a wild guess..). Mvh, /Fredrik Karlsson On Tue, Jan 27, 2004 at 06:02:53PM +0100, Giampiero Salvi wrote: I have problems running R with screen. For those who don't know, screen is a unix tool that is quite handy if you want to leave a process (that outputs to tty) running when you logout, and then recover the session later on. It works like this: 1) run 'screen': you get a normal prompt as if you were in a normal shell. 2) run whatever command you like 3) press 'C-a d' to detach the session. Now you can logoff if you like 4) when you want to recover the session type 'screen -r' The problem is that R seems to catch the 'C-a' signal, and nothing happens. Since there is no way to detach the screen, there is no use to it either. Is there a way around this problem?

[R] bartlett.test in a cell?
Dear list, I want to apply the bartlett test of homogenity of variance between two groups in a cell, which in turn is created by a number of factors. Is there a way to do this without having a zillion loops around the data? I've played around with tapply and aggregate, but it seems the problem with these approaches is that the 'groups' variable will have to be supplied. Any thoughts on how I might do this? /Fredrik __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] Help regarding repeated measures needed.
Dear list, I feel that I have to contact you for help with the data set I collected. It concerns longitudinal data from acoustic measurements conducted at monthly invervals during the development of a group of children. In the synchronic perspective, I have found that it is highly unlikely that the data is normally distributed. Furthermore, other studies have shown a decreasing variance with increasing age. So, what I want to ask you is: 1) What do I do with this data. Is it possible to do statistical analysis on this? 2) What approach do you recommend? What are the potential draw-backs? 3) Do you have some litterature suggestions for me? 4) If there is something that I can do, is it implemented in R? I'm sure that you can tell that I would be happy for any help I could get on this issue. /Fredrik Karlsson __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help

[R] RODBC sqlSave problem.
Dear list, Being new to both the postgres database, ODBC and the RODBC interface, I am somewhat confused by some of the problems I am experiencing trying to connect R to the database. Whai I am trying is basically the example part of the help file for the sqlSave function: library(RODBC) odbcConnect(theodor) - channel data(USArrests) sqlSave(channel, USArrests, verbose = TRUE) Query: CREATE TABLE USArrests (rownames varchar(255) ,Murder float8 ,Assault int4 ,UrbanPop int4 ,Rape float8 ) Error in sqlSave(channel, USArrests, verbose = TRUE) : [RODBC] ERROR: Could not SQLExecute When issuing this comamnd, a table is created in the specified database, with fields corresponding to names(USArrests), except in lower case, but the fiels contain no data. Does anyone know the reason for this? One of my guesses is that the table and field names are converted into lower cases by the database manager, which would result in an error due to non-existent symbols when RODBC tries to inser the data. Is this a possibility? Does anyone know how to investigate this? Are there alternative explanations? I would, of course, be extremely greateful for all the help I can get. /Fredrik Karlsson __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
