[R-sig-Geo] Adding raster files from a folder

[jon.skoien at jrc.ec.europa.eu]

Hi Sajid,

You should be able to do something like this:

setwd( name of folder)
fls = list.files() # you can add a pattern if you only want files of a 
certain type
dst = stack(fls[1])
for (ifile in 2:length(fls)) dst = addLayer(dst, raster(fls[ifile]))

And I am sure someone can do this even shorter...

Cheers,
Jon
