pcaplot3d: visualization of shape change

Description

visualization of the shape changes explained by Principal components

Usage

pcaplot3d(x,...)
## S3 method for class 'symproc':
pcaplot3d(x, pcshow = c(1, 2, 3), mag = 3, color = 4, lwd = 1,sym=TRUE,...)
## S3 method for class 'nosymproc':
pcaplot3d(x, pcshow = c(1, 2, 3), mag = 3, color = 4, lwd = 1,...)

Arguments

x

a object derived from the function procSym calculated on 3D coordinates.

pcshow

a vector containing the PCscores to be visualized.

mag

a vector or an integer containing which standard deviation of which PC has to be visualized.

color

color of the 3d points/spheres.

lwd

width of the lines representing the shape change.

sym

logical: if TRUE the symmetric component of shape is displayed. Otherwise the asymmetric one.

...

Additional parameters which will be passed to the methods.
