Uh, yes.  Get the syntax right.  Use R, when you are using R.

Looking at ?Syntax and ?Logic might help you a bit.

Other than that, there's not much that one can say without seeing a 
reproducible example.  And if you sat down and wrote out a *reproducible 
example*, using correct R syntax, you probably wouldn't need any 
assistance from R-help.

Have you read any of the readily available R tutorials?  If not do so. 
If so, read them again and actually take note of what they say!

cheers,

Rolf Turner
