I have used S-PLUS for years. Now I am learning to use R in
Windows'98. I downloaded the latest version and installed it as
instructed. However, I cannot find answers from online help to the
following questions I encountered. If any of you has quick answers
to these questions, please drop me a couple of lines. Thanks.
1. Why does R change my working directory during a session? I often
used getwd() to check my working directory and surprisingly found
that it was changed, and the location it changes to is quite random.
Has anybody encountered this problem? It is very annoying to check
and set my working directory whenever I want to save my work.
2. I downloaded ESS-5.1.18 and installed it in NTEmacs-20.4. It works
fine with S-PLUS 2000. However, if I use it with R, it is very very
slow and takes more than one minute to see the R prompt after M-x R.
After that, it seems OK. Why?
3. From the online documents, I often see descriptions related to
Rcmd. But there is no file in the Windows distribution of R named
Rcmd. Is it renamed Rterm.exe in Windows?
