coo_sample: Sample coordinates (among points)

In Momocs: Morphometrics using R

Sample coordinates (among points)

Description

Sample n coordinates among existing points.

Usage

coo_sample(coo, n)

Arguments

coo	either a matrix of (x; y) coordinates or an Out or an Opn object.
n	integer, the number fo points to sample.

Details

For the Out an Opn methods (pointless for Ldk), in an $ldk component is defined, it is changed accordingly by multiplying the ids by n over the number of coordinates.

Value

a matrix of (x; y) coordinates, or an Out or an Opn object.
