Use ggplot to plot a Raster* or a SpatRaster object.
A wrapper function around ggplot (ggplot2 package). Note that the function in the raster package is called gplot with a single 'g'.
## S4 method for signature 'Raster' gplot(x, maxpixels=50000,...) ## S4 method for signature 'SpatRaster' gplot(x, maxpixels=50000,...)
x |
A Raster* or SpatRaster object |
maxpixels |
Maximum number of pixels to use |
... |
Additional arguments for ggplot |

## Not run:
r <- raster(system.file("external/test.grd", package="raster"))
s1 <- stack(r, r*2)
names(s2) <- c('meuse', 'meuse x 2')
library(ggplot2)
theme_set(theme_bw())
## With raster
gplot(s1) + geom_tile(aes(fill = value)) +
facet_wrap(~ variable) +
scale_fill_gradient(low = 'white', high = 'blue') +
coord_equal()
## With terra
s2 <- rast(s1)
gplot(s) + geom_tile(aes(fill = value)) +
facet_wrap(~ variable) +
scale_fill_gradient(low = 'white', high = 'blue') +
coord_equal()
