Examples

# NOT RUN {
# WKT to WKB
## point
wkt_wkb("POINT (-116.4 45.2)")

## linestring
wkt_wkb("LINESTRING (-116.4 45.2, -118.0 47.0)")

## multipoint
### only accepts the below format, not e.g., ((1 2), (3 4))
wkt_wkb("MULTIPOINT (100.000 3.101, 101.00 2.10, 3.14 2.18)")

## polygon
wkt_wkb("POLYGON ((100.0 0.0, 101.1 0.0, 101.0 1.0, 100.0 0.0))")

# WKB to WKT
## point
(x <- wkt_wkb("POINT (-116.4 45.2)"))
