## Return Well-known Text representation of simple feature geometry

### Description

Return Well-known Text representation of simple feature geometry or coordinate reference system

### Usage

    st_astext(x, digits = options("digits"), ..., EWKT = FALSE)

    st_asewkt(x, digits = options("digits"))

### Arguments

`x` | object of class `sfg`, `sfc`, or `sf`
`digits` | integer; number of decimal digits to print
`...` | ignored
`EWKT` | logical; use PostGIS Enhanced WKT (includes srid)

### Details

The returned WKT representation of simple feature geometry conforms to the simple features access specification and extensions (if `EWKT = TRUE`), known as EWKT, supported by PostGIS and other simple features implementations for addition of SRID to a WKT string.

`st_asewkt()` returns the Well-Known Text (WKT) representation of the geometry with SRID meta data.

### Examples

    library(sf)
    pt <- st_sfc(st_point(c(1.0002,2.3030303)), crs = 4326)
    st_astext(pt, 3)
    st_asewkt(pt, 3)
