The centroid is the geometric mean of the vertices in a geometry. euclid supports centroid calculations for triangles, tetrahedrons and 2-4 points
Arguments
- x
A vector of triangles or tetrahedrons, or points if
y
,z
, ort
are provided- ...
arguments passed on to methods. Specifically the method for
euclid_geometry
vectors accept up to three additional vectors ofeuclid_point
(y
,z
, andt
arguments) ifx
is aeuclid_point
vector

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>
