grep() versus grepl()

[Maleeha]

In reference to the example in issue #11:

• R

  
  pax <- c("asdgf2", "asd3", "bcdfs4", "zsdfs5", "asdfs6", "podf-podf-podf-podf-podf")

regex <- "(^\D\D\D\D)|-\D\D\D\D|(^\D+)3"

- `grep` returns terms that contain matches:

grep(regex, pax, value=T) [1] "asdgf2" "asd3" "bcdfs4" "zsdfs5"
[5] "asdfs6" "podf-podf-podf-podf-podf"

- `grepl` returns whether the "terms with matches" are `TRUE` or `FALSE`

grepl(regex, pax) [1] TRUE TRUE TRUE TRUE TRUE TRUE

Thanks again for the review @wibeasley
