geo_set_z: Work with Z values

In paleolimbot/geovctrs: Efficient Data Structures for Geometry Vectors

Description

Currently, geovctrs supports X, Y, and Z coordinates. These functions extract, set, and drop Z values.

Usage

geo_set_z(x, z)

geo_drop_z(x)

geo_has_z(x)

geo_z_range(x, ..., na.rm = FALSE, finite = FALSE)

geo_z_envelope(x, ..., na.rm = FALSE, finite = FALSE)

Arguments

x	A geometry-like object, or one that can be coerced to a geometry-like object using as_geovctr().
z	A vector of z coordinate values.
...	Unused
na.rm	Should NAs be removed?
finite	Should only finite values be considered? TRUE implies na.rm = TRUE.

Value

A modified version of x.

Examples

geo_set_z(c("POINT (2 3)", "POINT Z (2 3 4)"), 10)
geo_drop_z(c("POINT (2 3)", "POINT Z (2 3 4)"))
geo_has_z(c("POINT (2 3)", "POINT Z (2 3 4)"))
geo_z_range(c("POINT (2 3)", "POINT Z (2 3 4)"), na.rm = TRUE)
geo_z_envelope(c("POINT (2 3)", "POINT Z (2 3 4)"), na.rm = TRUE)
