CenterPolygon: Computes the center of a given polygon. The center is obtained by averaging the x and y coordinates of the polygon

Description

CenterPolygon computes the center of a polygon

Usage

CenterPolygon(Poly)

Arguments

Poly

Polygon object, previously created with either of the functions CreatePolygon or CreateRegularPolygon

Value

Vector which contains the xy-coordinates of the center of the polygon

Examples

Run this code
# NOT RUN {
P1 <- c(0,0)
P2 <- c(1,1)
P3 <- c(2,0) 
Poly <- CreatePolygon(P1, P2, P3)
C <- CenterPolygon(Poly)
x_min <- -5
x_max <- 5
y_min <- -5
y_max <- 5
CoordinatePlane(x_min, x_max, y_min, y_max)
Draw(Poly, "blue")
Draw(C, "red")
# }
