pcaplot3d: visualization of shape variation

In Morpho: Calculations and Visualisations Related to Geometric Morphometrics

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,
  legend = TRUE,
  type = c("spheres", "points"),
  ...
)

## S3 method for class 'nosymproc'
pcaplot3d(
  x,
  pcshow = c(1, 2, 3),
  mag = 3,
  color = 4,
  lwd = 1,
  legend = TRUE,
  type = c("spheres", "points"),
  ...
)

Arguments

x	a object derived from the function procSym calculated on 3D coordinates.
...	Additional parameters which will be passed to the methods.
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.
legend	logical: if TRUE a legend explaining the color coding of the PCs is plotted.
type	character: for type="spheres", the landmarks will be rendered using rgl's spheres3d function and for type="points" by points3d respectivly.

Details

Value

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