You can also do `df1 %>% mutate(colIDs = str_remove("colIDs, "\\.\\d+$"))` — akrun, Apr 24 '19 at 13:03

You can do this with sub and a regular expression.

Data$colIDs = sub("\\..*", "", Data$colIDs)

\\. selects the (first) period and .* includes everything afterwards. These are replaced with the empty string.
