hist: Histogram

Description

Create a histogram of the values of a SpatRaster. For large datasets a sample of maxcell is used.

Usage

# S4 method for SpatRaster
hist(x, layer, maxcell=1000000, plot=TRUE, maxnl=16, main, ...)

Value

This function is principally used for plotting a histogram, but it also returns an object of class "histogram" (invisibly if plot=TRUE).

Examples

r1 <- r2 <- rast(nrows=50, ncols=50)
values(r1) <- runif(ncell(r1))
values(r2) <- runif(ncell(r1))
rs <- r1 + r2
rp <- r1 * r2

opar <- par(no.readonly =TRUE)
par(mfrow=c(2,2))
plot(rs, main='sum')
plot(rp, main='product')
hist(rs)
a <- hist(rp)

x <- c(rs, rp, sqrt(rs))
hist(x)
