quantile: Raster quantiles

In rspatial/raster: Geographic Data Analysis and Modeling

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

density, cellStats

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)
