R help - Jul 2003 - How to install a package

Dear R community:

My platform: R 1.7.0 + windows2000.

I am trying to install the package "lasso2" which I saw in the
following web address:
http://cran.us.r-project.org/src/contrib/PACKAGES.html#emplik. However, I failed
to install it from R menu "Packages| Install package(s) from CRAN"
since I
could not find this item in the list.

Thanks in advance!

The list in the menu consists of packages that have been compiled for
Windows.  It looks as though lasso2 won't compile for Windows without
modifications.  If you want to use it, you'll need to find a compiled
copy somewhere else, or compile it yourself.

Uwe, do you think it would be helpful to display this information from
Rgui?  That is, put the whole list of packages into the menu, but mark
some of them as unavailable and display the explanation if those are
selected?  I'd guess lots of Rgui users never look at the binary
directory themselves, they let Rgui do it.

In place of lasso2, Prof. Hastie's lars package (also on CRAN) can be used
(and it's faster, too).

Please read it!  Please also update to R 1.7.1.
