Discovering patterns in textual strings

R Help Forum

 

Is there a R library (or a way) that I can extract unique character strings,
or repeating patterns in textual strings.  Say for example I have the
following records:

 

Abc_1234_kjhksh_276

Abc

Abc_1234_lakdofyo_324

Bce_876_skdhk_*&^%*&

Bce

Bce_454

 

And I would like to see the following results

Abc

Abc_1234

Bce
