Convert Factors to Strings
step_factor2string will convert one or more factor
vectors to strings.

## S3 method for class 'step_factor2string'
tidy(x, ...)recipe |
A recipe object. The step will be added to the sequence of operations for this recipe. |
... |
One or more selector functions to choose which
variables will be converted to strings. See |
role |
Not used by this step since no new variables are created. |
trained |
A logical to indicate if the quantities for preprocessing have been estimated. |
columns |
A character string of variables that will be
converted. This is |
skip |
A logical. Should the step be skipped when the
recipe is baked by |
id |
A character string that is unique to this step to identify it. |

prep has an option strings_as_factors that
defaults to TRUE. If this step is used with the default
option, the string(s() produced by this step will be converted
to factors after all of the steps have been prepped.
An updated version of recipe with the new step
added to the sequence of existing steps (if any). For the
tidy method, a tibble with columns terms (the
columns that will be affected).
