In nat: NeuroAnatomy Toolbox for Analysis of 3D Image Data

Get and assign coordinates for classes containing 3D vertex data

Description

xyzmatrix gets coordinates from objects containing 3D vertex data

xyzmatrix<- assigns xyz elements of neuron or dotprops object and can also handle matrix like objects with columns named X, Y, Z or x, y, z.

Usage

xyzmatrix(x, ...)

## Default S3 method:
xyzmatrix(x, y = NULL, z = NULL, ...)

## S3 method for class 'neuron'
xyzmatrix(x, ...)

## S3 method for class 'neuronlist'
xyzmatrix(x, ...)

## S3 method for class 'dotprops'
xyzmatrix(x, ...)

## S3 method for class 'hxsurf'
xyzmatrix(x, ...)

## S3 method for class 'igraph'
xyzmatrix(x, ...)

## S3 method for class 'mesh3d'
xyzmatrix(x, ...)

xyzmatrix(x) <- value

## S3 replacement method for class 'neuron'
xyzmatrix(x) <- value

## S3 replacement method for class 'dotprops'
xyzmatrix(x) <- value

## S3 replacement method for class 'hxsurf'
xyzmatrix(x) <- value

## S3 replacement method for class 'igraph'
xyzmatrix(x) <- value

## S3 replacement method for class 'shape3d'
xyzmatrix(x) <- value

## S3 replacement method for class 'neuronlist'
xyzmatrix(x) <- value

Arguments

x	object containing 3D coordinates
...	additional arguments passed to methods
y, z	separate y and z coordinates
value	Nx3 matrix specifying new xyz coords

Details

Note that xyzmatrix can extract or set 3D coordinates in a matrix or data.frame that either has exactly 3 columns or has 3 columns named X,Y,Z or x,y,z.

Value

For xyzmatrix: Nx3 matrix containing 3D coordinates

For xyzmatrix<-: Original object with modified coords
