You can set values of a Raster* object, when i is a vector of cell numbers, a Raster*, Extent, or Spatial* object.
x[i] <- value
x[i,j] <- value
| Arguments: | ||
x |
a Raster* object | |
i |
cell number(s), row number(s), Extent, Spatial* object | |
j |
columns number(s) (only available if i is (are) a row number(s)) | |
value |
new cell value(s) | |
r <- raster(ncol=10, nrow=5) values(r) <- 1:ncell(r) * 2 r[1,] <- 1 r[,1] <- 2 r[1,1] <- 3 s <- stack(r, sqrt(r)) s[s<5] <- NA
