scale.neuron: Scale and centre neuron 3D coordinates

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

Scale and centre neuron 3D coordinates

Description

note that scale.dotprops recalculates the tangent vectors after scaling the 3D coords. See dotprops for details.

Usage

## S3 method for class 'neuron'
scale(x, center = TRUE, scale = TRUE)

## S3 method for class 'dotprops'
scale(x, center = TRUE, scale = TRUE)

Arguments

x	A neuron
center	3-vector to subtract from x,y,z coords
scale	3-vector used to divide x,y,z coords

Details

If scale=TRUE, the neuron will be rescaled to unit sd in each axis. If center=TRUE, the neuron will be centred around the axis means. See base::scale.default for additional details.

Value

neuron with scaled coordinates

Examples

n1.scaledown=scale(Cell07PNs[[1]],scale=c(2,2,3))
n1.scaleup=scale(Cell07PNs[[1]],scale=1/c(2,2,3))
