Problem with R 2.9.0 vs. R2.8.1 with either "survival" package or "predict" function
Just wanted to alert everyone regarding a problem that I only
experience with R2.9.0 and not with R2.8.1 when I run both using
exactly the same script and the same data.
Here is what I do with my data "MyData", 2 predictors (V1 and V2) and
my survival DV "Depvar":

Comparing two documents in the index
I want to compare two documents in the index (i.e. retrieve the cosine
similarity/score between two documents term-vector''s). Is this possible
using the standard Ferret functionality?
Thanks in advance,

Different behavior of model.matrix between R 3.2 and R3.1.1
Terry - your example didn't demonstrate the problem because the variable
that interacted with strata (zed) was not a factor variable.
But I had stated the problem incorrectly. It's not that there are too
many strata terms; there are too many non-strata terms when the variable
interacting with the stratification factor is a factor variable. Here
is a simple example, where I have

Missing dependencies in pkg installs
I had the same thought in the shower this morning but I was disappointed to find that SElinux was disabled on the system. My next step will be to install a previous version of R on the system. My problem is that I am planning a shiny server installation and at least half of the apps on the current system depend on these libraries that will not install.

Scraping a web page
I would like to be able to submit a list of URLs of various webpages and extract the "content" i.e. not the mark-up of those pages. I can find plenty of examples in the XML library of extracting links from pages but I cannot seem to find a way to extract the text. Any help would be greatly appreciated - I will not know the structure of the URLs I would submit in advance. Any

Missing dependencies in pkg installs SOLVED
So apparently (being a linux novice) I didn't realize it was insufficient to simply have the file marked as executable. It turns out the default TMP directory on my machine is mounted with a noexec flag so no files in that directory are allowed to be executed. The solution is to set an environment variable TMPDIR=some new directory I created (eg. /home/myusername/tmp) Then R uses that

Windows editor suggestions - autosave
I am looking for advice on an editor to use with R (windows) that has an autosave feature. I typically write scripts using the RGui (and tried TinnR yesterday) but I am having continuing problems with BSODs (non R related) and have in the past have had issues with R crashes and would really like a system that does not require me to remember to hit the save button on my script every 10 minutes so

Not much progress..... I step through debug and it gets to the do.install() function which immediately errors with the same "configuration not executable" error.
So, made a tempfunc that was a copy of tools:::.install_packages and edited the file_test("-x","configure") line to return a TRUE
now I get a Permission Denied error (even if I run as root)

Accessing functions in a library
I am trying to write a modified function to plot an rpart object. By
using getS3method I can see the plot and text code that I want to
modify. Since I don't want to modify the package, I create a new
function to plot the rpart object. The problem is that the original
function calls many rpart specific functions that are only visible
inside the rpart namespace. Therefore, when I call my

I believe that is a locally defined function, which means you can set a
breakpoint within it but only if R is compiled with source info, or you
can manually call

I don't know what is causing this bug. Perhaps a Linux user can
reproduce it and fix it.

Following Duncan's instructions I find that the system and R find that configure IS executable but if trying to install via install.packages I get the same error.
I also tried using R CMD INSTALL from the terminal and install.packages with a local file pointing to the very same tar.gz file that shows the executable bit set. All result in the same "configure is not executable" result.

Anyone successfully install Rgraphviz on windows with R 2.13?
I have been trying to get Rgraphviz to work (I know it is from Bioconductor) unsuccessfully. Since I have no experience with Bioconductor I thought I would ask here if anyone has advice. I have installed Graphviz 2.20.3 as is recommended on the Bioconductor site but basically R cannot seem to find the needed dll files. So, even though I have added the appropriate directories to the system path R

Help with evaluation of expressions
Hello all:
I have searched through the help files and I have been unsuccessful in
solving this problem.
I am trying to create a small wrapper function that will go around a

and also write the name of the file to a text file. The purpose is to
efficiently bring a large number of plots into powerpoint. I am using
