nodiv (version 1.4.2)

gridData: 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)

Value

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

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
