Interpolation to a regular grid via triangulation — tri_fun • guerrilla

Superseded by grid_barycentric(), which does the same thing under a name that says what it is.

Usage

tri_fun(xy, value, grid = NULL, duplicates = mean, ...)

Arguments

xy: coordinates
value: value to interpolate
grid: grid to use
duplicates: passed to grid_barycentric()
...: passed to grid_barycentric()

Value

A guerrilla_grid with values.

Examples

xy <- cbind(runif(50), runif(50))
grid_barycentric(xy, xy[, 1])  ## use this instead
#> <guerrilla grid>
#> dimension : 60, 50  (ncol, nrow) = 3000 cells
#> extent    : 0.03968992, 0.92577588, 0.04549673, 0.95116504  (xmin, xmax, ymin, ymax)
#> resolution: 0.01476810, 0.01811337
#> crs       : <none>
#> values    : 2745 of 3000 cells, 0.04707397 to 0.9183918
