.table_as_df: Results from table() as Data Frame

Description

Takes the results from table() and returns them as a data frame. After the table() results are made into a data frame, all the variables are made into character columns, and the function also restores the column types to their original classes. For strata columns, only observed combinations are returned.

Usage

.table_as_df(
  data,
  variable = NULL,
  by = NULL,
  strata = NULL,
  useNA = c("no", "always"),
  count_column = "...ard_n..."
)
