## Extract Centroid

### Description

`get_centroid` identifies the 2D centroid in a WKT object (or vector of WKT objects). Note that it assumes cartesian values.

### Usage

    wkt_centroid(wkt)

### Arguments

`wkt` | a character vector of WKT objects, represented as strings

### Value

a data.frame of two columns, `lat` and `lng`, with each row containing the centroid from the corresponding wkt object. In the case that the object is NA (or cannot be decoded) the resulting values will also be NA

### See Also

`wkt_coords` to extract all coordinates, and `wkt_bounding` to extract a bounding box.

### Examples

    wkt_centroid("POLYGON((2 1.3,2.4 1.7))")
    #  lng lat
    #1 2   1.3
