scoresequencearray: scoresequencearray

In deformetrics/deformetrics: R functions for shape analysis

Description

This function computes a sequence of shapes computed by deformed a reference shape ("mshape" argument) according to the eigenvectors specified in "rotation" argument. The sequence is computed in the interval between "from" and "to" argument. Usually the "rotation" argument comes from a PCA but any ordination method could be used.

Usage

scoresequencearray(mshape, from, to, pcn, rotation, mag = 1, frames = 15,
  type = 1)

Arguments

mshape	numeric: a kx2 matrix which will be deformed according to "from" and "to" values and to "rotation" eigenvectors.
from	numeric: a starting value for the computation od the sequence of shapes
to	numeric: the final value for the computation od the sequence of shapes
pcn	numeric: column number of "rotation" argument to be used to deform "mshape"
rotation	numeric: rotation
mag	numeric: magnification (default=1)
frames	numeric: number of frames to be saved (default=15)

Value

myarray array: an kxmxn array of predited shapes
