is.bool {terra} | R Documentation |
The values in a SpatRaster layer are by default numeric, but they can also be logical (Boolean), integer, or categorical (factor).
For a SpatRaster
, as.logical
and isTRUE
is equivalent to as.bool
. isFALSE
is equivalent to !as.bool
, and as.integer
is the same as as.int
.
See levels
and cats
to create categorical layers by setting labels.
