This generator supplies 0 or 1 value depending on the provided coordinates position on a checkerboard. The frequency determines the number of squares per unit.

gen_checkerboard(x, y = NULL, z = NULL, t = NULL, frequency = 1)

Arguments

x, y, z, t

The coordinates to get pattern from

frequency

The frequency of the generator

Value

A numeric vector

Examples

grid <- long_grid(seq(1, 10, length.out = 1000), seq(1, 10, length.out = 1000)) grid$chess <- gen_checkerboard(grid$x, grid$y) plot(as.raster(grid, chess))
