RemovePointPoly: Removes a point from a previously defined polygon

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

# NOT RUN {
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)
# }
