Pairs plot (matrix of scatterplots) — pairs • raster

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

Usage

# S4 method for class '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)


if (FALSE) { # \dontrun{
# to make indvidual histograms:
hist(r)
# or scatter plots:
plot(r, 1/r)
} # }
