RemovePointPoly: Removes a point from a previously defined polygon

In LearnGeom: Learning Plane Geometry

Description

RemovePointPoly creates a matrix to represent the polygon that connects several points

Usage

RemovePointPoly(Poly, position)

Arguments

Poly	Polygon object, previously created with function CreatePolygon or CreateRegularPolygon
position	Integer indicating the position of the point in the original polygon that is being removed. It is convenient to visualize the polygon with label = T in order to avoid mistakes

Value

Returns a matrix which contains the points of the polygon. Each row represents one of the points

Examples

x_min <- -5
x_max <- 5
y_min <- -5
y_max <- 5
CoordinatePlane(x_min, x_max, y_min, y_max)
n <- 5
C <- c(0,0)
l <- 2
Penta <- CreateRegularPolygon(n, C, l)
Penta <- RemovePointPoly(Penta, 4)
Draw(Penta, "blue", label = TRUE)
