I am trying to use regex (based on the new stringr cheat sheet) within my “select” to choose columns. However, it seems to not be working.
df1 %>% select(id, ends_with("\\d"))
is meant to select
id, as well as every column that ends in a digit (0-9). However, it seems to just get
id. I also tried wrapping it with brackets (and double brackets), but that doesn’t help.
Additionally I tried
df1 %>% select(id, ends_with("[:digits:]"))
but that also seems to just give me
id. (Additionally, I tried wrapping that in double brackets, but that did nothing).
Any suggestion on how to use regex within the select helpers like
