Creates a mask where a cell in any layer of r that is NA will be returned
as NA.
Details
Similar in intention to mask_all, but (a) will work on larger rasters
because it only holds the values of a single layer in memory at a time, and
(b) returns a mask layer, rather than masking each layer in r.
Can be very slow
Examples
r <- example_raster(seed = 10)
s <- example_raster(seed = 11)
r[10:20] <- NA
s[5:15] <- NA
q <- mask_from_all(c(r,s))
library("terra")
plot(c(r,s,q))
