[STATSGRASS] [R-spatial-devel] speed of GRASS/R interface

[Markus Neteler]

Today I downloaded 'sp' and 'spgrass6' from CVS (http://r-spatial.sf.net/),
steps here to enable more people to try:

# use empty password == <enter> key:
cvs -d:pserver:anonymous at r-spatial.cvs.sourceforge.net:/cvsroot/r-spatial
login
# fetch classes:
cvs -z3
-d:pserver:anonymous at r-spatial.cvs.sourceforge.net:/cvsroot/r-spatial co -P
sp
cvs -z3
-d:pserver:anonymous at r-spatial.cvs.sourceforge.net:/cvsroot/r-spatial co -P
spgrass6

# install from the same directory:
R CMD INSTALL sp
R CMD INSTALL spgrass6

Then I tried the new classes: INCREDIBLY FAST!

Seems that I can now start working with my satellite data
in R - thanks for this speedup!

best wishes,
Markus
