I'm using spsample() with a second SpatialLinesDataFrame but now I'm geting an error. This is what I do:
fl2300 <- readOGR(dsn="/media/Transcend/MONTSENY2008/MONTSENY_UAV2/flMatagalls300",layer="flMatagalls300")
wpMata300 <- spsample(fl2300[1,],33,offset=0.0,type="regular")
Error in proj4string(x) : proj4string only works for class(es extending) Spatial Nothing looks wrong with fl2300 (at least not different to other SPDFs for which spsample() works fine):
str(fl2)

Do I have anything wrong in this object? Thanks Agus
