Function to calculate focal values for a raster object using a matrix of weights.

Description

ra_focal has the effect of smoothing a raster object.

Usage

ra_focal(ra, weights, fun = mean, na.rm = FALSE, na.only = FALSE)

Arguments

ra	Raster object.
weights	A 3 by 3 matrix of values for the focal values.
fun	Function to use to sumamrise the focal values
na.rm	Should NAs be ommited from the summaries?
na.only	Should only cells with NAs be replaced with focal values?

Value

Raster object.
