scatterplot: Scatterplot of two SpatRaster layers

Description

Scatterplot of the values of two SpatRaster layers

Usage

# S4 method for 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
