opoly_i: Calculates shape from a polynomial model

Description

Returns a matrix of (x; y) coordinates when passed with a list obtained with opoly or npoly.

Usage

opoly_i(pol, nb.pts = 120, reregister = TRUE)
npoly_i(pol, nb.pts = 120, reregister = TRUE)

Arguments

pol

a pol list such as created by npoly or opoly

nb.pts

the number of points to predict. By default (and cannot be higher) the number of points in the original shape.

reregister

logical whether to reregister the shape with the original baseline.

Value

a matrix of (x; y) coordinates.

for (i in 2:7){
x <- opoly_i(opoly(o, i))
