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