pcaplot3d: visualization of shape variation

Description

visualization of shape change

Usage

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

Value

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

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

visualization of the shape changes explained by Principal components
