quantile: Quantiles of spatial data

Description

Compute quantiles for each cell across the layers of a SpatRaster.

You can also use this method to compute the quantiles of the numeric variables of a SpatVector.

Usage

# S4 method for SpatRaster
quantile(x, probs=seq(0, 1, 0.25), na.rm=FALSE, filename="", ...) 
# S4 method for SpatVector
quantile(x, probs=seq(0, 1, 0.25), ...)

Arguments

x

SpatRaster or SpatVector

probs

numeric vector of probabilities with values in [0,1]

na.rm

logical. If TRUE, NA's are removed from x before the quantiles are computed

filename

character. Output filename

...

additional arguments for writing files as in writeRaster

Value

SpatRaster with layers representing quantiles

Examples

# NOT RUN {
r <- rast(system.file("ex/logo.tif", package="terra"))   
r <- c(r/2, r, r*2)
q <- quantile(r)
q

# same but slower
# qa <- app(r, quantile)
# }
