[R-sig-Geo] Get map of non-NA cells of a stack

[Johannes Radinger]

Hi,

I have several stacks with different numbers of raster maps. All the stacked rasters have some NA-cells but sometimes in different locations. I'd like to create a raster map of a single stack which indicates cells that are populated in all rasters of that stack (all non-NA cells).

Is there a special function within the raster package?

Best regards
Johannes
