[Rd] Wishlist: install.packages to look for the newest version (PR#13853)

[groemping at bht-berlin.de]

Uwe,

I am talking binaries and Windows. I was not thinking of building 
binaries for old versions, but of looking in the new version 
repositories first, whether there is a binary that is said to be valid 
for the older version. Wouldn't it be possible to have the process look 
up a table of a newer R version for compatible binaries ?
I got stuck with R 2-8.1 (which is not that old and should not have 
stopped building binaries yet, has it?), where the binary install 
installs version 0.2 from the Austrian repository although version 0.3 
has been around for almost a month and version 0.4-1 is current.

As a workaround, I could at least refer people who are willing to test 
my current (quickly changing) design packages to the install command 
that allows them to install the packages from the newer repository 
without upgrading their R version. Could you help me out with that 
command ? I searched quite a bit and remember a help entry by you, but 
did not find anything any more about the syntax of install.packages for 
this purpose.

Regards, Ulrike
