[R] how to ignore NA with "NA" or "NULL"

[Jeff Newmiller]

Please read the posting guide mentioned at the bottom of every message.

You might also benefit from reading http://stackoverflow.com/questions/5963269/how-to-make-a-great-reproducible-example. We would certainly benefit from not having to guess what problems you are really encountering.

Also, it seems that you refer to in-memory data as "files"... this is imprecise and confusing. Learn to use the str() function to know what kinds of objects you are referring to... in this case I believe you are referring to data frames.
