data.frame transformation
...t of "data" make a new dataframe, where the cells of value
"1" in the species columns ("species1" to "species3") are replaced by
the respective "lat" values automatically - so that the final dataframe
looks like this:
specieslat1<-c(0,0,0,15)
specieslat2<-c(10,12,0,0)
specieslat3<-c(10,12,13,15)
data.frame(cbind(grid.id,lat,specieslat1,specieslat2,specieslat3))
?
Thanks a lot,
cheers
