Scatterplot of two SpatRaster layers — scatterplot • terra

Scatterplot of the values of two SpatRaster layers

Usage

# S4 method for class 'SpatRaster,SpatRaster'
plot(x, y, maxcell=100000, warn=TRUE, nc, nr, 
   maxnl=16, smooth=FALSE, gridded=FALSE, ncol=25, nrow=25, ...)

Arguments

x: SpatRaster
y: SpatRaster
maxcell: positive integer. Maximum number of cells to use for the plot
nc: positive integer. Optional. The number of columns to divide the plotting device in (when plotting multiple layers)
nr: positive integer. Optional. The number of rows to divide the plotting device in (when plotting multiple layers)
maxnl: positive integer. Maximum number of layers to plot (for multi-layer objects)
smooth: logical. If TRUE show a smooth scatterplot
gridded: logical. If TRUE the scatterplot is gridded (counts by cells)
warn: boolean. Show a warning if a sample of the pixels is used (for scatterplot only)
ncol: positive integer. Number of columns for gridding
nrow: positive integer. Number of rows for gridding
...: additional graphical arguments

Examples

s <- rast(system.file("ex/logo.tif", package="terra"))   
plot(s[[1]], s[[2]])

plot(s, sqrt(s[[3:1]]))
