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)
.
quantile(x, ...)
A vector of quantiles
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.
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)
