[R] GPS data!

[Spencer Graves]

        Have you tried "sos":


install.packages('sos') # if not already installed
library(sos)
(gps <- ???GPS)


       This found 63 matches for me right now.  The results open as a 
table in a web browser with the package with the most matches first and 
with hot links to the help page for each match in the right hand column.


       Hope this helps.
       Spencer
