Pairs plot (matrix of scatterplots)
Pair plots of layers in a RasterStack or RasterBrick. This is a wrapper around graphics function pairs.
## S4 method for signature 'RasterStackBrick' pairs(x, hist=TRUE, cor=TRUE, use="pairwise.complete.obs", maxpixels=100000, ...)
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 |

Argument passed to the |
