What is 'somehat obscure' about (?install.packages)
See Also:
'installed.packages', 'remove.packages'
See 'download.file' for how to handle proxies and other options to
monitor file transfers.
? Indeed, where would you expect to find information about downloading
files if not under download.file?
Far too often I think we get no credit for implementing such arcane
things, nor for documenting them.

Honest, I tried to find notes in the archives on this one. Maybe I used
the wrong keywords.
With sys 10.4.11, Intel iMac, I installed R 2.8.1 directly from the dmg
installer package.
After that, I tried to install some R packages. Due to port blocking at
work, I have to download the files, unpack, and install from my local
directory.
Using the R.app GUI, I selected "Install at System Level" and get an error
message something like
" 'lib' variable not found, using default {my local Library/Frameworks
directory}..."
The default value of libPaths was
[1] "/Users/carl/Library/R/2.8/library"
[2] "/Library/Frameworks/R.framework/Versions/2.8/Resources/library"
If I ran the command
R> .libPaths(.libPaths()[2])
{thus removing the reference to my local tree}
then the GUI properly installed to the system library tree.
So, is there a better, or simpler, way to make this happen?
Why not simply set up the appropriate http proxy? The information is
included in the somewhat obscure location in the help page for
"download.file". Alternatively, there is some information on the topic in
the Windows FAQ. This should allow you to use the usual tools for
installing packages.
