raster_resample: Resample spatial configurations within a regular grid

In cszang/raresa: Spatial resampling of clustered data.

Description

Divide region into regular grid cells and sample sites from each grid cell.

Usage

raster_resample(x, size = 5, n = 5, lambda = 3)

Arguments

x	a data.frame with as least lon and lat as decimal degrees as variables
size	how big (in degrees) should the grid cells for resampling be?
n	how many resampling configurations shall be computed?
lambda	lambda parameter for poisson distribution that gives count of sites per grid cells

Details

A regular grid of given size is superimposed on sampling design, and the individual plots are attributed to specific grid cells. Then, from each grid cell a poisson distributed number of sites is selected randomly, and a list of new resampled configurations of the original data is returned.
