Thanks Julian, it was that the resolution of the shift was too small
compared to the original raster.

Hi Julian,
Your input raster myraster does not change! Have a look at your output
raster eff. Also your "shift" is to small compared to your Raster
Resolution to result in "extended data"
Try:
ex <- extent(myraster)+100
eff <- expand(myraster, ex)
extent(eff)
Best,
Julian

Dear list,
I cannot figure this out. I am trying to extend a raster object,
using the "extend" function (from the raster package), but the
extension of the raster does not change. Here is an example:
##############################
set.seed(100)
myraster <- raster(ncols=4, nrows=4)
myraster[] <- sample(1:10,ncell(eff),replace=T)
extent(myraster)
ex <- extent(myraster)+2
eff <- expand(myraster, ex)
extent(myraster)
##############################
As you can see, the extent of "myraster" does not change. What I
am doing wrong?
Many thanks,
Julian
