Many thanks Ivan


Use is.na() on getValues() outputs, combine the two masks using the | operator
to get a mask of values that are missing in either raster, then negate the mask
to choose the non-missing values:

all.equal(getValues(r1)[!mask], getValues(r2)[!mask])

--> what do you mean by use is.na() in getValues(). So I need to call
getValues a second time? I suppose you mean to first prepare a mask using is.na
without getValues and then in the second step your code?

Kind regards
Sibylle
