pcaplot3d: visualization of shape variation

Description

visualization of shape change

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.

Value

• returns an invisible array containing the shapes associated with the Principal components selected.

Details

visualization of the shape changes explained by Principal components
