convexify

Description

order coordinates based on their angle around a central point

Usage

convexify(xside, yside, indx, indy, order = FALSE)

Arguments

xside	vector of x coordinates
yside	vector of y coordinates
indx	central point x coordinate
indy	central point y coordinate
order	logical - if TRUE return order only and not the coordinates

Details

For rasterisation, the shape of the polygon must be as convex as possible. To ensure that all points are in some sense in a convex form we order them based on their polar coordinate angle.

Value

a data frame of ordered x and y coordinates.
