Hello, Could someone recommend a good book on regular expressions with focus on applications/use as it might relate to R. I remember there was a mention of such a reference book recently, but I could not locate that message on the archive.

Quite often I save misc functions and data objects as .RData files that I can use in other sessions. Although I could 'Load Workspace" these files, most of the times I prefer attaching them. It would be really convenient to have a menu item under the File menu on the Windows R Console to allow attaching workspaces, e.g. -------------------- Attach Workspace... Load Workspace... Save

Hi, I am trying to use dynamic memory allocation in the C code to be called by R through the .C interface. I have used R_alloc as explained in the Writing R Extensions and included the R.h header. The program compiles fine but fails when linking. Obviously it needs a library file where R_alloc is found. I have tried to link by adding R.dll to list of files at the end of the link command but

Hi, I was wondering if there is a direct approach for lining up 2-column matrices according to the values of the first column. An example and a brute-force approach is given below: x <- cbind(1:10, runif(10)) y <- cbind(5:14, runif(10)) z <- cbind((-4):5, runif(10)) xx <- seq( min(c(x[,1],y[,1],z[,1])), max(c(x[,1],y[,1],z[,1])), 1) w <- cbind(xx, matrix(rep(0, 3*length(xx)),

I can reproduce this in MDI. Another clue is that as the pager for ?merge is opened, the font in the console changes. The console is still working: commands you type in it are accepted. So the issue appears to be that the font in use has been changed incorrectly (and it seems that the C code thinks it has been changed in the preferences dialog).

This might be an trivial thing but I am stuck.

Hello, I've been trying to plot a subscript in a text formula using plotmath but I haven't been able to do so. In my example below I would like the text label to show X[min] = 10.1 +/- 5.5 Here is the code: ll <- c(x=10.1, sde=5.5) plot(1:10) text(x=9, y=2, pos=2, expression(paste(X[min], "=", paste(ll, collapse="+/-")))) This works fine up to the inner paste

This is interesting: The crash does not happen if I run Rgui in MDI mode. The crash seemed to only occur in SDI.

The crash happens if I browse to a folder on a mapped drive. I.e., if I type in

Dear altogether, I want to blank the lower (or upper) part of a correlation matrix as it is done by dist() example: ( d <- cor(matrix(runif(12),nrow=4)) ) If I do the following d[lower.tri(d)] <- "" of course everything is changed to character - that's not what should be. Additionally, it does not work to assign "0" or anything else. The same is true for

Full_Name: Byron Ellis Version: 1.2.3 OS: Windows 2000 Server Submission from: (NULL) (140.247.105.95) In Rgui when attempting to resize the console the system locks for a second (cursor locks up, etc) and then either returns to normal for a second before crashing or just crashes when we start moving again (the former happens more often when making things bigger, the latter when the console is

Hi, Although this is not directly an R-related question, it is relevant as I am trying to port some R code to C to speed things up in a computation. I am working through my first attempts to generate and link compiled C code in R. I could make the 'convolve' function to work and similar functions that take vectors as arguments. In my application I need to pass a couple of matrices to

I am developing a package that imports some functions from another package. The imported package (qcc) does not have a namespace and this is causing problems with loading of my package, which has a namespace. Is there a workaround to allow loading the namespace-less package? I searched the archives and found a suggestion that the package should be included in the Depends list, but this has not

Hi, I am totally new to Linux and trying to install R and related tools. I downloaded the rpm files for el4/x86_64 from the CRAN repository and tried to run rpm but it did not go through complaining about dependencies. Do all the listed rpm files need to be installed? What is the order in which these need to be installed? I appreciate any help with this or any suggestions for alternate ways

Hi everyone, Can anyone give me more details about the 'lp', 'risk', 'terms', and 'expected' options from the predict.coxph function? I actually found that risk is obtained from exp(lp). I can't find information on 'expected' type however. Is anybody can expand the information on this function? Thank you in advance, I will appreciate it.

Hi All, Does someone have an idea of how to cleverly convert a categorical timeseries into a transition matrix? Ie, I have something like: x<- c(1,1,2,1,1,2,2,2,1,2), And I want a matrix with counts and/or probabilities: > tr <- matrix(c(2,3,2,2),2,2) > tr [,1] [,2] [1,] 2 2 [2,] 3 2 Meaning that there are two transitions from 1 to 1, two from 1 to 2, three from 2 to 1
