I am wondering if there has been a solution to the following issue with R
under Windows (see also thread to PR#6662 in this mailing list:
I am using R for teaching students Statistics, so they are working with a
university-wide installation of R. I have compiled an R-library which
contains all the instructions and customised functions for the course and the
students have been using it successfully under UNIX for the last 5 years. I
keep the library in my own space which is pointed to in R_LIBS variable
defined for the students. I myself not a sysadmin for the university network,
so I cannot install to the system-wide library directory, but this was not a
matter. This year, I have to (sniff-sniff) switch to Windows platform and the
following problem arose.
The library loads fine and the text-style help files show OK, but help.start()
reports the following error:
Error in file(f.tg, open = "w") : unable to open connection
In addition: Warning messages:
1: cannot update HTML package index in: make.packages.html(lib.loc)
2: cannot open file `C:\Progra~1\R\rw1071/doc/html/search/index.txt'
The index-file is opening but does not contain links to my library.
As far as I understand, the problem lies in the lack of write permissions for
the system directory where R is installed. While UNIX version creates the
html-help files in per-session way in the user's home directory, the windows
version atempts to modify the system-wide file.
Having possibility to display html-help would be a great benefit, as the
students can follow the links present there which is impossible from within
"inline" help. So my question:
Is there any work-around that problem? Would making creation of html help
files in the users' space under Windows as under UNIX/linux resolve the
issue? Or maybe, it's already been fixed in the recent version of R?
Thanks in advance for your help! Please, make a copy of your response to my
