centroid: Centroid of a convex polygon

Description

Computes Centroid of a convex polygon in plane.

Usage

centroid(x, y=NULL,...)

Arguments

x

The data as a matrix, data frame or list. If it is a matrix or data frame, then each row is viewed as one bivariate observation. If it is a list, all components must be numerical vectors of equal length (coordinates of observations).

y

The data as a matrix, data frame or list. If it is a matrix or data frame, then each row is viewed as one bivariate observation. If it is a list, all components must be numerical vectors of equal length (coordinates of observations).

...

For future use.

Value

Returns with respect to data set, the centroid point in plane.

Details

In dimension 2, calculates centroid of a convex polygon.
