make_recode_query: Make a recoding call from linked codings

Description

This creates a function that accepts a vector and recodes it from the information provided in a `linked_coding_df`. Usually this is intended for package authors who want to operate at the recoding relational table level (e.g. mapping multiple codings to one). Most end users should use [recode_vec()] instead.

Usage

make_recode_query(linked_codings, from = 1, to_suffix = "to", ...)

Value

A function with single argument when applied to an input vector will recode the vector appropriately

Arguments

linked_codings

A `linked_coding_df`

from

A character or integer that selects the correct original coding. Defaults to 1, the first linked coding.

to_suffix

The suffix used to signify which columns refer to values to which the vector will be recoded

...

Any other parameters passed onto the recoding function selector

Examples

cdng_old <- coding(code("Yes", 1), code("No", 2))
cdng_new <- coding(code("Yes", 1), code("No", 0))
recode_func <- make_recode_query(link_codings(cdng_new, cdng_old))

vec <- sample(1:2, 20, replace = TRUE)
recode_func(vec)
