I only want to keep obs where the length of the id string is either 11
or 12 characters
long. I know I can solve this in a more cumbersome manner using the
-regex- machinery,
but I was hoping for a more succinct solution using string functions.
Unfortunately,
I'm having a mental block with choosing the appropriate function.
Suggestions would be
appreciated.
