Thanks Uwe,
The problem, however, is not solved. If I do:
download.file("http://gbi.agrsci.dk/statistics/courses/2011-ISMLS-course/data/LiSciData_0.0-03.tar.gz";,
tempdir())
Error in
download.file("http://gbi.agrsci.dk/statistics/courses/2011-ISMLS-course/data/LiSciData_0.0-03.tar.gz";,
:
cannot open destfile 'c:\temp\RtmpcrQ0WM', reason 'Permission denied'
However, if I specify a filename then things are working:
download.file("http://gbi.agrsci.dk/statistics/courses/2011-ISMLS-course/data/LiSciData_0.0-03.tar.gz";,
paste(tempdir(),"thisfile",sep="\\"))
trying URL
'http://gbi.agrsci.dk/statistics/courses/2011-ISMLS-course/data/LiSciData_0.0-03.tar.gz'
Content type 'application/x-tar' length 315847 bytes (308 Kb)
opened URL
downloaded 308 Kb
dir(tempdir())
[1] "thisfile"
According to to the documentation:
"Destfile A character string with the name where the downloaded file is saved.
Tilde-expansion is performed."
I read the documentation such that I can specify a directory in which the file
is to be put, but I may be wrong; or is it possible that there is a bug
somewhere?
Best regards
Søren

Right, install.packages assumes a package name or a file path. URLs (or
any othr connections) are not supported.

If you want to use it as a repository, you have to make such a
repository. For a source repository, create subdirs ./src/contrib and
put your package there. Afterwards, you can run tools::write_PACKAGES on
that directory in order to create PACKAGES and PACKAGES.gz files for
that repository.
> 3) If I put the package in the Rs working directory then the following works:

Right, hence you can also tell your students to:
download.file("http://gbi.agrsci.dk/statistics/courses/2011-ISMLS-course/data/LiSciData_0.0-03.tar.gz";,
tempdir())
install.packages(file.path(tempdir(), 'LiSciData_0.0-03.tar.gz'),
repos=NULL, type='source')
