(1) Don't post in html.

(2) Don't send code that makes use of packages that you don't mention
(in this case "data.table").

(3) Don't use "data" as the name of a data object.  There is a base 
function called "data" whence you run the risk of getting toadally 
incomprehensible error messages as the result of certain syntax errors.
Also see fortune("dog").

cheers,
