[R] text vector clustering

[Ed Merkle]

Srinivas,

I don't know of a clustering algorithm, but you might check out agrep() 
from the base package and stringMatch() from the MiscPsycho package. 
These can help to identify similar text sequences, and it may be 
possible to group similar names by using these commands over and over again.
