Hi,
I am working on a stand-alone Linux Redhat machine, which is disconnected
to outside...But I need R to be installed on the machine....
The only way available, so far as I know, is to download all the packages
first and then copy to the machine and finally install them locally...
But how can I download all the packages instead of using the
install.packages(....) ?
The simplest way is to create a local CRAN mirror, then use a file://
URL to refer to it.
The part of CRAN you need is ca 2GB at present. I use an rsync script
something like
rsync -rvCtL --delete --include="*.tar.gz" --include="PACKAGES*"
--exclude="*/*" cran.r-project.org::CRAN/src/contrib .
(so as not to mirror the 16GB Archive) and access it via
contriburl="file:///.../R/packages/contrib"
Thanks
Xiong
