is.bool {terra}R Documentation

Raster value types

Description

The values in a SpatRaster layer are by default numeric, but they can also be logical (Boolean), integer, or categorical

Note that as.bool and as.int return a new SpatRaster, whereas is.bool and is.int return a logical value for each layer. For a SpatRaster, isTRUE is equivalent to as.bool, isFALSE is equivalent to !as.bool, as.integer is the same as as.int and as.logical is the same as as.bool

Usage

## S4 method for signature 'SpatRaster'
is.bool(x)
## S4 method for signature 'SpatRaster'
as.bool(x, filename, ...)
## S4 method for signature 'SpatRaster'
is.int(x)
## S4 method for signature 'SpatRaster'
as.int(x, filename, ...)

Arguments

x

SpatRaster

filename

character. Output filename

...

list with named options for writing files as in writeRaster

Value

logical or SpatRaster

Examples

Run examples
