raster (version 3.1-5)

image: Image

Description

Create an "image" type plot of a RasterLayer. This is an implementation of a generic function in the graphics package. In most cases the plot function would be preferable because it produces a legend (and has some additional options).

Usage

image(x, ...) 
# S4 method for RasterLayer
image(x, maxpixels=500000, useRaster=TRUE, ...)
# S4 method for RasterStackBrick
image(x, y=1, maxpixels=100000, useRaster=TRUE, main, ...)

Arguments

x

Raster* object

maxpixels

integer > 0. Maximum number of cells to use for the plot. If maxpixels < ncell(x), sampleRegular is used before plotting

useRaster

If TRUE, the rasterImage function is used for plotting. Otherwise the image function is used. This can be useful if rasterImage does not work well on your system (see note)

main

character. Main plot title

...

Any argument that can be passed to image (graphics package)

y

If x is a RasterStack or RasterBrick: integer, character (layer name(s)), or missing to select which layer(s) to plot

Examples

# NOT RUN {
r <- raster(system.file("external/test.grd", package="raster"))
image(r)
# }
