wk_set_z: Set coordinate values

Description

Set coordinate values

Usage

wk_set_z(handleable, z, ...)
wk_set_m(handleable, m, ...)
wk_drop_z(handleable, ...)
wk_drop_m(handleable, ...)
wk_trans_set(value, use_z = NA, use_m = NA)

Arguments

handleable

A geometry vector (e.g., wkb(), wkt(), xy(), rct(), or sf::st_sfc()) for which wk_handle() is defined.

z, m

A vector of Z or M values applied feature-wise and recycled along handleable. Use NA to keep the existing value of a given feature.

...

Passed to the wk_handle() method.

value

An xy(), xyz(), xym(), or xyzm() of coordinates used to replace values in the input. Use NA to keep the existing value.

use_z, use_m

Used to declare the output type. Use TRUE to ensure the output has that dimension, FALSE to ensure it does not, and NA to leave the dimension unchanged.

Examples

# NOT RUN {
wk_set_z(wkt("POINT (0 1)"), 2)
wk_set_m(wkt("POINT (0 1)"), 2)
wk_drop_z(wkt("POINT ZM (0 1 2 3)"))
wk_drop_m(wkt("POINT ZM (0 1 2 3)"))

# }
