Can I specify where the sources downloaded to build R packages are going

I know how to specify where packages I install via install.packages or R CMD are going. When I install within R I always get the 

The downloaded source packages are in
    ‘/tmp/RtmpxtIlp5/downloaded_packages’

Can I setup some environment or something so it always go where I want it to go ?

EDIT Not sure if this is new but the good answer is to use destdir

install.packages(pkgs='versions', destdir='/tmp/sources', lib='/tmp/library', dependencies=TRUE, repos='http://cran.us.r-project.org')

I use the script install.r included as an example in the littler package (which is also available as a binary for several Linux distrubtions including Debian and Ubuntu). As a side-effect, it leaves packages in /tmp/download_packages:

edd@max:~$ install.r digest
trying URL 'http://cran.rstudio.com/src/contrib/digest_0.6.8.tar.gz'
Content type 'application/x-gzip' length 97985 bytes (95 KB)
==================================================
downloaded 95 KB

* installing *source* package ‘digest’ ...
** package ‘digest’ successfully unpacked and MD5 sums checked
** libs
gcc -I/usr/share/R/include -DNDEBUG   [...]
gcc -I/usr/share/R/include -DNDEBUG   [...]
[...]
gcc -shared -L/usr/lib/R/lib [...]
installing to /usr/local/lib/R/site-library/digest/libs
** R
** inst
** preparing package for lazy loading
** help
*** installing help indices
** building package indices
** testing if installed package can be loaded
* DONE (digest)

The downloaded source packages are in
        ‘/tmp/downloaded_packages’
edd@max:~$

As they are not delete (as done by the default R session) you could easily script it to copy them to some other directory.

You can use the dir argument of install. Like so:

install.packages("yourPackage", dir="your/install/dir")

There is no global option in Rstudio for that argument. I poked around in the R directory, and couldn't find anything. As a global workaround:

installDir = "your/install/dir"
...
install.packages("yourPackage", dir=installDir)

Not ideal, but it will work.
