Ok, thanks for the answer. It must be a problem of disk space.
I'll try what you say.

Mathieu/Carsten,
Carsten's suggestion is also good:
elev<-overlay(detm@layers[[1]],detm@layers[[2]],
fun=function(a,b) {return(a-b)} )
although I would do:
elev<-overlay(detm, fun=function(a,b) {return(b-a) } ,
filename="disk/with/space.tif")

Hi,
I have a RasterStack detm composed of a dem and a dtm.
I wanted to apply the difference between dem and dtm so as to get the
elevation.
But I got the following message (in French):
Erreur dans result[, i] <- readBin(raster@file@con, what = dtype, n =
ncols, :
