Get Tile Centroids

Get the centroids of the tiles. For spatialTilePlan, these will be returned as SpatVector centroids. For non-spatial plans like pixelTileGrid, this will be returne as a matrix.

Usage

# S4 method for class 'tilePlan'
centroids(x, fun = function(x) x, offset = c(0, 0), zero = FALSE, ...)

# S4 method for class 'freeTilePlan'
centroids(x, ...)

# S4 method for class 'pointTilePlan'
centroids(x, ...)

# S4 method for class 'pixelTilePlan'
centroids(x, fun = function(x) x, zero = TRUE, ...)

# S4 method for class 'spatialTilePlan'
centroids(x, zero = FALSE, ...)

Arguments

x

tilePlan

fun

(internal) post-processing function used to convert centroids to expected output. Such as vect() for spatialTilePlan

offset

numeric of length 2. x and y values to offset by. Default is c(0, 0).

zero

logical. Whether to zero out padding effects. (used by default with pixelTilePlan)

...

additional params to pass.
