Convert columns of type character to factors based on a set of rules. By default columns will be converted for small datasets (<= 100 rows) with more rows than unique values. For larger datasets, columns are converted only when the number of unique values is <= 100 and there are 30 or more rows in the data for every unique value

Examples

tibble(a = c("a", "b"), b = c("a", "a"), c = 1:2) %>% to_fct()
