Create sf object from two-column matrix

Question

I have a simple two-column matrix that I want to convert to an sf object where each row specifies a point:

> set.seed(123);m=matrix(runif(10)         


        

Answer 1

As per the sf docs

m %>% 
  as.data.frame %>% 
  sf::st_as_sf(coords = c(1,2))
