R packages

I have now installed a R package repository on our webserver.
The main reason was, that I wanted a R repository, such that our courses data package
can be installed straightforwardly using the install.packages funtion.

In the directory on our web server

/usr/home/biomet/public_html/software/r/packages

findes en subdirectory structure
bin > windows> contrib > 2.2
and in the lowest direcotry you find
1) zip filen af den datapackage datRep we use in our courses
2) PACKAGES file, that is just a file containing the contents of the DESCRIPTION file of
the packages in this directory.


You access the directory from the net via:
http://gbi.agrsci.dk/biometry/software/r/packages


It is possible to install the data-package from R by
install.packages("dataRep",repos="http://gbi.agrsci.dk/biometry/software/r/packages")

We need to discuss how we mange the package repository in future.

Whenever a new -zip file is added to the directory, the PACKAGES file has to be updated.

Someone adding a package has to do two steps

a) copy his zip file to
/usr/home/biomet/public_html/software/r/packages/bin/windows/2.2
b) running the function write_PACKAGES of the tools package

write_PACKAGES("/usr/home/biomet/public_html/software/r/packages/bin/windows/2.2")

I think, this functions has to be executed in R on the unix machine.

(At the moment I do everything on my PC and copy everything to the web-sever)



I hope that my initiative was not too premature.
