In rspatial/raster: Geographic Data Analysis and Modeling

Box plot of Raster objects

Description

Box plot of layers in a Raster object

Usage

## S4 method for signature 'RasterStackBrick'
boxplot(x, maxpixels=100000, ...)

## S4 method for signature 'RasterLayer'
boxplot(x, y=NULL, maxpixels=100000, ...)

Arguments

x	Raster* object
y	If x is a RasterLayer object, y can be an additional RasterLayer to group the values of x by 'zone'
maxpixels	Integer. Number of pixels to sample from each layer of large Raster objects
...	Arguments passed to graphics::boxplot

Examples

r1 <- r2 <- r3 <- raster(ncol=10, nrow=10)
values(r1) <- rnorm(ncell(r1), 100, 40)
values(r2) <- rnorm(ncell(r1), 80, 10)
values(r3) <- rnorm(ncell(r1), 120, 30)
s <- stack(r1, r2, r3)
names(s) <- c('A', 'B', 'C')

boxplot(s, notch=TRUE, col=c('red', 'blue', 'orange'), main='Box plot', ylab='random' )
