[GRASS-user] error in example

[Paolo Cavallini]

Hi all.
I'm following the examples in:
http://casoilresource.lawr.ucdavis.edu/drupal/node/438
but I get an error in:
new_data <- SpatialGridDataFrame(grd, data=data.frame(k=rep(1,G$cols*G$rows)),
proj4string=CRS(x at proj4string@projargs))

Error in validityMethod(object) :
  unequal number of objects in full grid and data slot

Any hint?
Thanks a lot.

BTW: the link to sample data should be changed to
http://mirrors.ibiblio.org/grass/sampledata/spearfish_grass60data-0.3.tar.gz
