convert_to_integer: 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)

Value

Nothing. A raster with the same name as x (it may overwrite it) but without the file extension, if one exists.

Arguments

x

A raster layer in 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")
stream_shp <- system.file("extdata", "streams.shp", package = "rdwplus")

# Set environment parameters
set_envir(dem)
raster_to_mapset(rasters = dem)
vector_to_mapset(vectors = stream_shp)
 
# Rasterise the streams
out_name <- paste0(tempdir(), "/streams_rast.tif")
rasterise_stream("streams", out_name, overwrite = TRUE)

# Convert to integer
convert_to_integer("streams_rast.tif")
}
