map_data_: Create a mapping without NSE

In metacoder: Tools for Parsing, Manipulating, and Graphing Taxonomic Abundance 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)

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.

Value

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

Examples

x = c("d" = "looks like a cat", "h" = "big scary cats",
      "i" = "smaller cats", "m" = "might eat you", "n" = "Meow! (Feed me!)")
map_data_(ex_taxmap, from = ex_taxmap$taxon_names(), to = x)
