Create a target grid for interpolation

Superseded by grid_spec(), which returns a plain list rather than a RasterLayer, and which takes its size as dimension = c(ncol, nrow).

Usage

defaultgrid(xy, ncols = 60, nrows = 50, prj = NA)

Arguments

xy

coordinates

ncols

number of columns

nrows

number of rows

prj

projection metadata, NA (the default) for none

Value

A guerrilla_grid, from grid_spec().

Examples

xy <- cbind(c(0, 4, 10), c(0, 2, 5))
grid_spec(xy)  ## use this instead
#> <guerrilla grid>
#> dimension : 60, 50  (ncol, nrow) = 3000 cells
#> extent    : 0, 10, 0, 5  (xmin, xmax, ymin, ymax)
#> resolution: 0.1666667, 0.1000000
#> crs       : <none>
#> values    : <none>
