quadrats.pp3: Divide a 3D Point Pattern into Sub-Volumes

In aproudian2/rapt: Atom Probe Tomography Analysis

Divide a 3D Point Pattern into Sub-Volumes

Description

Divides volume into quadrats and returns them.

Usage

quadrats.pp3(X, nx = 5, ny = nx, nz = ny, box.dims = NULL)

Arguments

X	The pp3 object to split up.
nx, ny, nz	Number of rectangular quadrats in the x, y, and z directions, if you wish to split up your point patthern by number of boxes.
box.dims	Vector containing the dimensions of the subsetted 3D boxxes, if you wish to define the individual boxx size. Use either nx, ny, nz or box.dims, but not both. See Details.

Details

If box.dims is not commensurate with the size of the object, the quadrats are justified toward the smallest boundary in each dimension (i.e. (c(min(x), min(y), min(z)))).

Value

A list containing the split up "pp3" objects.
