Sample random points in a stratfied manner from a raster with/out replacement

Description

This function is a robust version of sampleStratified() in the raster package where sampling can be performed with replacement in each stratum. Each unique value in a raster is identified as a stratum. Each stratum is sampled a given number of times.

Usage

sampleRastStrat(x, n, adjArea = TRUE, replace = TRUE)

Arguments

x	Raster* object.
n	number of points to sample from *each* stratum
adjArea	Logical. If TRUE then adjust sample probability of cells by cell area.
replace	Logical. If TRUE then sample with replacement.

Value

2-column matrix with longitude and latitude of random points.
