convert_to_integer {rdwplus} | R Documentation |
Convert a raster to integer format
Description
Given a raster in float, double or any other format, this function will convert it to integer format. This can be important because it is often an unstated requirement of GRASS modules such as the one for zonal statistics.
Usage
convert_to_integer(x, out)
Arguments
x |
A raster layer in the current GRASS mapset. |
out |
Name of the output raster. Avoid names with hyphens. |
Value
Nothing. A raster with the name out
will be added to the current GRASS mapset.
Examples
# Will only run if GRASS is running
if(check_running()){
# Load data set
dem <- system.file("extdata", "dem.tif", package = "rdwplus")
# Set environment
set_envir(dem)
# Make an integer-valued version of 'dem.tif'
convert_to_integer("dem.tif", "int_dem.tif")
# Compare
plot_GRASS("dem.tif")
plot_GRASS("int_dem.tif")
}
