strip_for_formula

<p>character vector of potential formula variables</p>

<p>This excludes many symbols, so just strip all symbols leaving
  alphanumeric, and no whitespace.</p>

This is a set of simple utilities for various data
manipulation and testing tasks.  The goal is to use core R tools well,
without bringing in many dependencies. Main areas of interest are
semi-automated data frame manipulation, such as converting factors in
multiple binary indicator columns. There are testing functions which
provide 'testthat' expectations to permute arguments to function
calls. There are functions and data to test extreme numbers, dates,
and bad input of various kinds which should allow testing failure and
corner cases, which can be used for fuzzing your functions. The test
suite has many examples of usage.
