str_replace applying to more than one column with mutate_at


I want to apply this function to several columns but I get an error

  mutate_at(.vars = vars(rp_tsn, rp_tsr, rp_tso, rp_total_cost, rp_parts_cost)
            .funs = funs(str_replace(., ",", ".")))

suggestions are welcome

Could you please turn this into a self-contained reprex (short for reproducible example)? It will help us help you if we can be sure we're all working with/looking at the same stuff.


If you've never heard of a reprex before, you might want to start by reading the help page. The reprex dos and don'ts are also useful.

What to do if you run into clipboard problems

If you run into problems with access to your clipboard, you can specify an outfile for the reprex, and then copy and paste the contents into the forum.

reprex::reprex(input = "fruits_stringdist.R", outfile = "")

For pointers specific to the community site, check out the reprex FAQ.
