Description

Transfer vector data to a raster

Usage

# S4 method for SpatVector,SpatRaster
rasterize(x, y, field, fun, background=NA,
   update=FALSE, touches=is.lines(x), filename="", overwrite=FALSE, wopt=list(), ...)

Arguments

x

SpatVector

y

SpatRaster

field

character, numeric, or missing. If field is a character, it should a variable name in x or vector of values if fun can handle these. If field is numeric it should be a single number (index the variable), or a vector with the same length as x. If it is missing, 1:nrow(x) is used

fun

function

background

numeric. Value to put in the cells that are not covered by any of the features of x. Default is NA

touches

logical. If TRUE, all cells touched by lines or polygons will be updated, not just those on the line render path, or whose center point is within the polygon

update

logical. If TRUE, the values of the SpatRaster are updated for the cells that overlap with the geometries of x. Default is FALSE

filename

character. Output filename. Optional

overwrite

logical. If TRUE, filename is overwritten

wopt

list. Options for writing files as in writeRaster

...

additional arguments passed on to fun

Value
