Get focal values
Get a matrix in which each row had the focal values of a cell. These are the values of a cell and a rectangular window around it.
## S4 method for signature 'SpatRaster' focalValues(x, w=3, row=1, nrows=nrow(x), fill=NA)
x |
SpatRaster or SpatVector |
w |
window. The window can be defined as one (for a square) or two odd numbers (row, col); or with an odd sized matrix |
row |
positive integer. Row number to start from, should be between 1 and nrow(x) |
nrows |
positive integer. How many rows? |
fill |
numeric used as values for imaginary cells outside the raster |
matrix
r <- rast(ncol=4, nrow=4, crs="+proj=utm +zone=1 +datum=WGS84") values(r) <- 1:ncell(r) focalValues(r)
