How to identify string with dots and number?

[Visiting]

There is a variable with some values like abcd...134, flextime...258, treatment...625, etc. the last 6 digits are three dots plus three numbers. Is there a easy way to identify all such pattern values? Thank you!

You can use str_detect() from the stringr package to return TRUE or FALSE if the pattern is matched. I stored a set of possible strings in the vector called Var.

library(stringr)
Var <- c("abcd...134", "flextime...258", "treatment...625",
  "abcd", "..134", "...13")
str_detect(Var, "\\.{3}\\d{3}$")
#> [1]  TRUE  TRUE  TRUE FALSE FALSE FALSE
