A tile grid drawn without cell borders — the right choice for a dense
heatmap or an image, where borders would swamp the data.
geom_raster(mapping = NULL, data = NULL, color = NULL, alpha = NULL)
Value
A Layer to add with +.
Examples
g <- expand.grid(x = 1:20, y = 1:20)
g$z <- as.vector(outer(1:20, 1:20, function(a, b) sin(a / 3) * cos(b / 3)))
ggnext(g, aes(x, y, color = z)) + geom_raster()
#> <ggnext plot>
#> data: 400 x 3
#> aes: x = x, y = y, color = z
#> layers: 1
#> coord: cartesian
#> mode: static
