Simulates xy coordinates for a circle of given radius. Created for package testing purposes, but might be useful for others.
sim_circle(r = 1, n = 100, mid = c(0, 0))Arguments
- r
Radius of the circle (default 1).
- n
Number of xy coordinates defining the circle (default 100).
- mid
Mid point of the circle (default 0, 0).
Value
A data frame of n xy-coordinates.
Examples
circ <- sim_circle()
plot(circ)
circularity(circ)
#> [1] 0.9998321
perimeter(circ)
#> [1] 6.282131
