lattice install (PR#1972)

[ripley@stats.ox.ac.uk]

Note the R version (1.3).

grid and lattice have been part of the Windows binary distribution since
1.4.0.  grid depends critically on the R version, so don't change it
unless you know exactly what you are doing.

library() in  1.6.0 will do a lot more checks of the package to be loaded.

Nope.  What packages are available depends on the current .libPaths(),
hence can only be known at load time.  There has been a long-term plan
that installing a package would also install its dependencies, but
the dynamic nature of R libraries (the dirs in which packages are
installed) makes this tricky.
