R: Examples for 'sfheaders::sf

### ** Examples


x <- cbind(x = 1:2, y = 3:4, linestring_id = 1)
sf_line( x )

  linestring_id   geometry
1             1 1, 2, 3, 4

x <- data.frame( linestring_id = rep(1:2, each = 2), x = 1:4, y = 4:1 )
(sfx <- sf_line( x ))

  linestring_id   geometry
1             1 1, 2, 4, 3
2             2 3, 4, 2, 1

## we trivially round-trip with sf_line()
sf_line(sf_to_df(sfx))

  linestring_id   geometry
1             1 1, 2, 4, 3
2             2 3, 4, 2, 1
