I tried using the Packages menu to install the gam package and get the following
output:

> local({a <- CRAN.packages()
+ install.packages(select.list(a[,1],,TRUE), .libPaths()[1], available=a,
dependencies=TRUE)})

package 'gam' successfully unpacked and MD5 sums checked

Delete downloaded files (y/N)? y

Warning message: 
unable to move temp installation 'H:/rw2000/library\file15762/gam' to
'H:/rw2000/library/gam'

I get the same message if I opt to delete the downloaded files and the same
problem if I try to install from a downloaded .zip file instead - not really
surprising as seems to "unpack" file okay, but loses the temporary file. As the
syntax of the file path for the temporary file is incorrect, I'm assuming this
is a bug in install.packages or one of the functions it calls...
