Hi Janet,

This question would probably be more suited for the r-sig-geo mailing
list. In my view, the best option is to use a tool like wgrib to dump
the layer you want from the grib file to text and then read it into R
using e.g. read.table. See also the spatial data classes provided to R
through the sp-package. A good book on spatial data in R is the book by
Bivand et al [1]. The spatial task view is another good source of
information [2].

regards,
Paul
