Raster quantiles

Description

Compute quantiles for the cell values of a RasterLayer. If you want to compute quantiles for each cell across a number of layers, you can use calc(x, fun=quantile).

Usage

quantile(x, ...)

Arguments

`x`	Raster object
`...`	Additional arguments: `na.rm=TRUE`, `ncells=NULL`, and additional arguments to the stats::quantile function, see `quantile`

ncells can be used to set the number of cells to be sampled, for very large raster datasets.

Value

A vector of quantiles

Examples

r <- raster(ncol=100, nrow=100)
values(r) <- rnorm(ncell(r), 0, 50)
quantile(r)
quantile(r, probs = c(0.25, 0.75), type=7,names = FALSE)
