2D random field binning

Description

Generate a bined matrix given a 2D random field.

Usage

vbin.grid(x, y, z, nx, ny, FUN = mean, na = NA)

Arguments

x, y, z	a random field with location vectors (x, y) and value vector z. They must have the same length.
nx, ny	the number of bins in x and y dimension.
FUN	a function to calculate statistics in each 2D bin.
na	Replacemnet for NA value in matrix bins.

Value

a matrix with row (column) names being the center points of x (y) dim, and with cell value being the aggregate statistics calculated by FUN.
