R: Correct Incorrectly Oriented WKT Objects

wkt_correct {wicket} | R Documentation

## Correct Incorrectly Oriented WKT Objects

### Description

`wkt_correct` does precisely what it says on the tin, correcting the orientation of WKT objects that are improperly oriented (say, back to front). It can be applied to WKT objects that, when validated with `validate_wkt`, fail for that reason.

### Usage

    wkt_correct(x)

### Arguments

`x` | a character vector of WKT objects to correct

### Value

a character vector, the same length as `x`, containing either the original value (if there was no correction to make, or if the object was invalid for other reasons) or the corrected WKT value.

### Examples

    # A WKT object
    wkt <- "POLYGON((30 20, 10 40, 45 40, 30 20), (15 5, 5 10, 10 20, 40 10, 15 5))"

    # That's invalid due to a non-default orientation
    validate_wkt(wkt)

    # And suddenly isn't!
    wkt_correct(wkt)
