map_data_: Create a mapping without NSE

Description

Creates a named vector that maps the values of two variables associated with taxa in a [taxonomy()] or [taxmap()] object without using Non-Standard Evaluation (NSE). Both values must be named by taxon ids. This is the same as [map_data()] without NSE and can be useful in some odd cases where NSE fails to work as expected.

obj$map_data(from, to)
map_data(obj, from, to)

Value

A vector of `to` values named by values in `from`.

Arguments

obj

The [taxonomy()] or [taxmap()] object.

from

The value used to name the output. There will be one output value for each value in `from`.

to

The value returned in the output.

Examples

      "i" = "smaller cats", "m" = "might eat you", "n" = "Meow! (Feed me!)")
