Create a barplot of the values of 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, ...)A numeric vector (or matrix, when beside = TRUE) of the coordinates of the bar midpoints, useful for adding to the graph. See barplot
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
f <- system.file("ex/elev.tif", package="terra")
r <- rast(f)
barplot(r, digits=-1, las=2, ylab="Frequency")
op <- par(no.readonly = TRUE)
par(mai = c(1, 2, .5, .5))
barplot(r, breaks=10, col=c("red", "blue"), horiz=TRUE, digits=NULL, las=1)
par(op)
