Hello,
I installed R on Windows Terminal Server (a variant of NT) from the binary
release. This is my first encounter with R. I have two questions.
The initialization time is very long, several minutes between clicking on the
"R 1.7.0" icon and getting to the ">" prompt. During
that time, the machine appears to be idle.
When it finally comes ready, I'm presented with a warning that might be
related:
[...]
Type `q()' to quit R.
> x <- rnorm(50)
Warning message:
package nls in options("defaultPackages") was not found
Given that the CPU is idle during the delay, it seems likely R is waiting for,
and timing out on, some resource. Can I perhaps restrict or display what
happens at initialization? It may be I don't need whatever it is that's
causing the delay.
FWIW, the machine is a dual-processor Pentium something @ 450 MHz w/ 512 MB RAM.
The second question is simple: How do I list the installed packages? I
haven't found the answer in the "Introduction to R" or the data
reference. I would just like to confirm that the ODBC package is included in
the Win32 release binary.
My next step is to hook up R to our database and compare its performance to
SAS's. Some of my colleagues had bad experiences with S some years ago, and
are wary of using R for that reason.
Thank you for your kind attention.

[Duncan Murdoch advised me offlist. Thanks for your help, Duncan. I tried to reply directly but your spam filter doesn't like my corporate email setup.] I turned off all the initialization options I could, and set --verbose. It seems like each step is slow, rather than racing to one point and stopping for a long time. The machine is behind a firewall with an http proxy, and I haven't found out how (if possible) to tell R about it. Does that matter at startup time? Trying to add a package yields:> local({a <- CRAN.packages()+ install.packages(select.list(a[,1],,TRUE), .libPaths()[1], available=a)}) trying URL `http://cran.r-project.org/bin/windows/contrib/1.7/PACKAGES' unable to connect to 'cran.r-project.org' on port 80. Error in download.file(url = paste(contriburl, "PACKAGES", sep = "/"), : cannot open URL `http://cran.r-project.org/bin/windows/contrib/1.7/PACKAGES' even though that URL works fine in IE. I understand I should be able to use Rcmd to install packages, but its perl scripts appear to be missing: $ rcmd --version Can't open perl script "D:\Programs\R\rw1070/bin/--version": No such file or directory Among the commands listed in in the appendix, the only installed script is rw1070\bin\BATCH. At the moment, it seems: 1. I cannot install packages via Rgui, because I don't have nonproxied access to the internet. 2. I cannot install packages via Rcmd. What to do? Thanks very much. --jkl ----------------------------------------- The information contained in this transmission may contain privileged and confidential information and is intended only for the use of the person(s) named above.

A little RTFM time found the "install from a zip file" option. I'm still stuck wrt the start up time, though. thanks. --jkl ----------------------------------------- The information contained in this transmission may contain privileged and confidential information and is intended only for the use of the person(s) named above.
