Create a barplot of the values of a the first layer of a SpatRaster. For large datasets a regular sample with a size of approximately maxcells is used.
# S4 method for SpatRaster
barplot(height, maxcell=1000000, digits=0, breaks=NULL, col, ...)SpatRaster
integer. To regularly subsample very large datasets
integer used to determine how to round the values before tabulating. Set to NULL or to a large number if you do not want any rounding
breaks used to group the data as in cut
a color generating function such as rainbow (the default), or a vector of colors
additional arguments for plotting as in barplot
A numeric vector (or matrix, when beside = TRUE) of the coordinates of the bar midpoints, useful for adding to the graph. See barplot
# NOT RUN {
f <- system.file("ex/elev.tif", package="terra")
