Calculate the centroid of a geometry or a set of points

The centroid is the geometric mean of the vertices in a geometry. euclid supports centroid calculations for triangles, tetrahedrons and 2-4 points

Usage

centroid(x, ...)

Arguments

x

A vector of triangles or tetrahedrons, or points if y, z, or t are provided

...

arguments passed on to methods. Specifically the method for euclid_geometry vectors accept up to three additional vectors of euclid_point (y, z, and t arguments) if x is a euclid_point vector

Value

a vector of points

Examples

p <- point(c(1, 5, 6), c(1, -2, 4))
# centroid of triangle
t <- triangle(p[1], p[2], p[3])
centroid(t)
#> <2D points [1]>
#> [1] <x:4, y:1>

plot(t, col = "grey", border = NA)
euclid_plot(centroid(t), pch = 16, cex = 2, col = "firebrick")


# Same as providing the points directly
centroid(p[1], p[2], p[3])
#> <2D points [1]>
#> [1] <x:4, y:1>
