pairs: Pairs plot (matrix of scatterplots)

In terra: Spatial Data Analysis

Pairs plot (matrix of scatterplots)

Description

Pair plots of layers in a SpatRaster. This is a wrapper around graphics function pairs.

Usage

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

Arguments

x	SpatRaster
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
maxcells	integer. Number of pixels to sample from each layer of a large SpatRaster
...	additional arguments (graphical parameters)

boxplot, hist

Examples

r <-rast(system.file("ex/elev.tif", package="terra"))
s <- c(r, 1/r, sqrt(r))
names(s) <- c("elevation", "inverse", "sqrt") 
pairs(s)

# to make indvidual histograms:
hist(r)
# or scatter plots:
plot(s[[1]], s[[2]])
