R: Pairs plot (matrix of scatterplots)

pairs {terra} | R Documentation

## 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)

### See Also

`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]])
