scatter function

Scatterplot of two SpatRaster layers

Scatterplot of the values of two SpatRaster layers methods

## S4 method for signature '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]]))
