Data wrangling with R

Question

I have a long list of variables that I want to convert to factors. So, I did this:

factor_df <- original_df %>%
                  select(PhoneService:PaymentMethod) %>%
                  map(as.factor)

I get all the variables from PhoneService to PaymentMethod as factors.
How do I make this factor_df to attach to original_df again, so that the original_df has all the appropriate data types?

Do you want to do the conversion for all character variables? If so, see https://stackoverflow.com/a/39582737/210673 for use of `mutate_if`. — Aaron left Stack Overflow, Apr 20 '18 at 20:47
Alternatively, look at `mutate_at` to convert only specific columns — Calum You, Apr 20 '18 at 21:11

original_df %>%
    mutate_at(vars(PhoneService:PaymentMethod), as.factor)

The dplyr::mutate_at() function allows you to specify which variables or vars() you wish to apply a single function or multiple functions with funs().
