In raster: Geographic Data Analysis and Modeling

Pairs plot (matrix of scatterplots)

Description

Pair plots of layers in a RasterStack or RasterBrick. This is a wrapper around graphics function pairs.

Usage

## S4 method for signature 'RasterStackBrick'
pairs(x, hist=TRUE, cor=TRUE, use="pairwise.complete.obs", maxpixels=100000, ...)

Arguments

x	RasterBrick or RasterStack
hist	Logical. If TRUE a histogram of the values is shown on the diagonal
cor	Logical. If TRUE the correlation coefficient is shown in the upper panels
use	Argument passed to the cor function
maxpixels	Integer. Number of pixels to sample from each layer of large Raster objects
...	Additional arguments (only cex and main)

Examples

r <- raster(system.file("external/test.grd", package="raster") )
s <- stack(r, 1/r, sqrt(r))
pairs(s)

## Not run: 
# to make indvidual histograms:
hist(r)
# or scatter plots:
plot(r, 1/r)

## End(Not run)
