| Subject | st: only keep obs of determinate string length |
| Date | Wed, 30 Jan 2013 10:47:43 -0700 |
Hello all, I'm drawing a blank on what should be a ridiculously easy problem. I have a unique string id var. Values in this var vary from 8-16 characters in length. 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.
