snake_case: Convert variable names to snake_case

In OuhscBbmc/OuhscMunge: Data Manipulation Operations

Convert variable names to snake_case

Description

This function attempts to convert variables to snake_case, even if it's already in snake_case. The important regex lines were posted by Stack Overflow user epost in "Elegant Python function to convert CamelCase to snake_case?".

Usage

snake_case(x)

Arguments

x	A vector of names to convert.

Value

A vector of converted names.

Note

This series of regexes has an advantages over the current implementations of lettercase::str_snake_case() and snakecase::to_snake_case(). The former converts "PatientDOB" to "patientdob" and the latter converts "patient.dob" to "patient_._dob". I'll keep an eye on these packages (i.e., lettercase #1 for 'camelCase' and snakecase #101). I'd prefer to use one of them, instead of maintaining the functions.
