Plot a grid — plot.guerrilla

Draw the grid with graphics::image(). No raster class is involved, which is the point: a grid is a dimension, an extent and a vector of values, and that is enough to draw it.

Usage

# S3 method for class 'guerrilla_grid'
plot(x, col = grDevices::hcl.colors(24, "YlGnBu"), asp = 1, ...)

Arguments

x: a guerrilla_grid with values
col: colours
asp: aspect ratio; 1 by default, or use NA to fill the device
...: passed to graphics::image()

Value

x, invisibly.

Examples

xy <- cbind(runif(50), runif(50))
g <- grid_barycentric(xy, xy[, 1] + xy[, 2])
plot(g)
