gridData: Apply a grid (2D bins) to nodiv objects of type 'points'

In nodiv: Compares the Distribution of Sister Clades Through a Phylogeny

Apply a grid (2D bins) to nodiv objects of type 'points'

Description

Takes an object of type distrib_data or nodiv_data, and puts the point distributions on a grid. Can also be used for resampling grid data at a coarser scale. If the comm matrix has abundances (any one value larger than 1), they are summed across points in the grid cell.

Usage

gridData(dist_data, cellsize_x = 1, cellsize_y = cellsize_x, xll_corner, yll_corner)

Arguments

dist_data	An object of type distrib_data or nodiv_data
cellsize_x	The size of the bins along the X (longitudinal) axis, in units of the spatial coordinates of the original points
cellsize_y	The size of the bins along the Y (latitudinal) axis, in units of the spatial coordinates of the original points
xll_corner	The x coordinate of the lower left corner of the lower left grid cell of the intended grid. The corner must be left of all points in the data set
yll_corner	The y coordinate of the lower left corner of the lower left grid cell of the intended grid. The corner must be below all points in the data set

Value

The return value is the original dist_data object with gridded distribution data
