xyzmatrix: 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, ...)
# S3 method for default
xyzmatrix(x, y = NULL, z = NULL, ...)
# S3 method for neuron
xyzmatrix(x, ...)
# S3 method for neuronlist
xyzmatrix(x, ...)
# S3 method for dotprops
xyzmatrix(x, ...)
# S3 method for hxsurf
xyzmatrix(x, ...)
# S3 method for igraph
xyzmatrix(x, ...)
# S3 method for mesh3d
xyzmatrix(x, ...)
xyzmatrix(x) <- value
# S3 method for neuron
xyzmatrix(x) <- value
# S3 method for dotprops
xyzmatrix(x) <- value
# S3 method for hxsurf
xyzmatrix(x) <- value
# S3 method for igraph
xyzmatrix(x) <- value
# S3 method for shape3d
xyzmatrix(x) <- value
# S3 method for neuronlist
xyzmatrix(x) <- value

Value

For xyzmatrix: Nx3 matrix containing 3D coordinates

For xyzmatrix<-: Original object with modified coords

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.
