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

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

Content type 'application/x-tar' length 315847 bytes (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."
A little ambiguous, but I guess it is the full path of the downloaded
file; 'destfile' and not 'destdir'.
Perhaps you mean tempfile() (a file name that can be created in R's
temporary directory) rather than tempdir() (R's temporary directory).
Otherwise you are trying to open for writing a location that is an
in-use directory, and Windows is saying that you can't do that.
Right, I was simply wrong in my suggestion that I had not tested before
sending it.

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

Can't get installing a package source (.tar.gz) from a web page to
work...

I have created an R-package with datasets which I want my students
to install (the package is not on CRAN).
1) I've put the package on the web in a directory called 'data' and
I thought I could do:

Right, install.packages assumes a package name or a file path. URLs
(or any othr connections) are not supported.
2) I've then put the package in data/src/contrib/ and try:
install.packages('LiSciData_0.0-03.tar.gz',repos='http://gbi.agrsci.dk/statistics/courses/2011-ISMLS-course/data/',
type='source')
Warning: unable to access index for repository
http://gbi.agrsci.dk/statistics/courses/2011-ISMLS-course/data/src/contrib
Warning message:
In getDependencies(pkgs, dependencies, available, lib) : package
'LiSciData_0.0-03.tar.gz' is not available (for R version 2.13.1)
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:
install.packages("LiSciData_0.0-03.tar.gz",repos=NULL,type="source")
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')
Best wishes, Uee
I would much prefer if it could be done directly from the web in
the spirit of attempt 1) above (because then fewer things can go
wrong for the students). Any hint on what I am doing wrong?
