In rasterVis: Visualization Methods for Raster Data

Use ggplot to plot a Raster* or a SpatRaster object.

Description

A wrapper function around ggplot (ggplot2 package). Note that the function in the raster package is called gplot with a single 'g'.

Usage

## S4 method for signature 'Raster'
gplot(x, maxpixels=50000,...) 
## S4 method for signature 'SpatRaster'
gplot(x, maxpixels=50000,...) 

Arguments

x	A Raster* or SpatRaster object
maxpixels	Maximum number of pixels to use
...	Additional arguments for ggplot

Examples

 
## Not run: 
library(raster)
library(terra)

r <- raster(system.file("external/test.grd", package="raster"))

s1 <- stack(r, r*2)
names(s1) <- 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(s2) + geom_tile(aes(fill = value)) +
          facet_wrap(~ variable) +
          scale_fill_gradient(low = 'white', high = 'blue') +
          coord_equal()
