Examples

library(terra)
d <- vect(system.file("ex/nigeria.json", package="phyloregion"))
e <- ext(d)

set.seed(1)
m <- data.frame(lon = runif(1000, e[1], e[2]),
                lat = runif(1000, e[3], e[4]),
                sites = seq(1000))
m <- vect(m)
z <- selectbylocation(m, d)
plot(d)
points(m, col = "blue", pch = "+")
points(z, col = "red", pch = "+")
