Dear R'sians.. I apologize if this topic has been beaten to death and hope that hawks don't pounce on me!
Could you please suggest an efficient way to filter rows from 500+ text files (some with 30000+ rows with multiple section table headers) residing in several folders? I guess probably "scan" is the fastest way to scan a file, but, I noticed it sometimes takes a long time when reading large text files. Would really appreciate your suggestions.
