geo_unnest: Unnest recursive geometry structures

In paleolimbot/geovctrs: Efficient Data Structures for Geometry Vectors

Description

Unnest recursive geometry structures

Usage

geo_unnest(x, ..., keep_empty = FALSE, keep_multi = TRUE, max_depth = 1)

## Default S3 method:
geo_unnest(x, ..., keep_empty = FALSE, keep_multi = TRUE, max_depth = 1)

## S3 method for class 'wk_wkt'
geo_unnest(x, ..., keep_empty = FALSE, keep_multi = TRUE, max_depth = 1)

## S3 method for class 'wk_wkb'
geo_unnest(x, ..., keep_empty = FALSE, keep_multi = TRUE, max_depth = 1)

## S3 method for class 'wk_wksxp'
geo_unnest(x, ..., keep_empty = FALSE, keep_multi = TRUE, max_depth = 1)

## S3 method for class 'data.frame'
geo_unnest(x, ..., keep_empty = FALSE, keep_multi = TRUE, max_depth = 1)

Arguments

x	A geometry-like object, or one that can be coerced to a geometry-like object using as_geovctr().
...	Unused
keep_empty	If TRUE, a GEOMETRYCOLLECTION EMPTY is left as-is rather than collapsing to length 0.
keep_multi	If TRUE, MULTI* geometries are not expanded to sub-features.
max_depth	The maximum recursive GEOMETRYCOLLECTION depth to unnest.

Examples

geo_unnest("GEOMETRYCOLLECTION (POINT (1 2), POINT (3 4))")
geo_unnest("GEOMETRYCOLLECTION EMPTY")
geo_unnest("GEOMETRYCOLLECTION EMPTY", keep_empty = TRUE)

geo_unnest(geo_example_wkt, keep_multi = TRUE)
geo_unnest(geo_example_wkt, keep_multi = FALSE)
