When I filter a dataframe using dplyr, there is an extra step that I need to perform (see code below). can I do something to not have this last row?

df <- df_1 %>%
  filter(col_1 %in% mylist) %>%
  select(col_2) %>%
  unique()
df <- df$col_2 # extra step

Both cols are of type chr.

Use `... %>% pull(col_2) %>% unique()` instead. If not working, please give a reproducible example. – markus Sep 26 '18 at 08:49
btw: you could also: `df_1 %>% filter(col_1 %in% mylist) %>% select(col_2) %>% unique() %>% .[["col_2"]]`. I recommend using markus way. – Andre Elrico Sep 26 '18 at 09:00
Did you try %<>% operator? – Naive_Natural2511 Sep 26 '18 at 12:16
