Hi,

I have created a data frame in R using the attached example. I stripped down some data so that I can attach the file. How can I search a Data frame in R by specifying values for columns TICKER and DCLRDT. Once the search is complete for that particular row I want to return the difference between columns RET and vwretd.

Thanks

I can't help you, but just wanted to point out that it looks like you forgot to attach anything.

I would go with RSQLite and make database from CSV, then use common SQL to retrieve parts of data you need.
