inflate: inflates a convex polygon

Description

Inflates a convex polygon

Usage

inflate(x, y=NULL, factor=2, ...)

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).

factor

An integer by default set to 2.

...

For future use.

Value

Returns nothing.
