Hi I am using Ubuntu Hardy, and I installing many packages from source. I am keeping my R packages fairly up to date. My question is: is there a way, of keeping the source packages, so that when I am installing a new version of R, an update.packages(checkBuilt=TRUE) will only fetch the packages when newer ones are available, but otherwise will use the local copies? To rephrase it, is it possible to have some kind of local repository for the source packages which are installed, so that only packages are downloaded when newer ones are available? I could use destdir to specify the directory in which to save the source files of the packages, but how can I use this directory as a first choice, and only download if a newer version exists? Rainer
I think it won't work out of the box, but you can do it with little efforts. The probably easiest way is to
1) make the local directory of source packages a repository by adding a PACKAGES file using write_PACKAGES() from package tools, 2) choose your local repository first on the list of repositories and second a repository on a CRAN and/or BioC mirror etc., 3) use update.packages() and it will grab from your first repository if there is no repository with a newer version number.
