[R] static analysis tools for R code?

An R script will terminate when one tries to use an undefined variable, with a message such as

Error in print(x) : Object "x" not found

This run-time error might occur after the script has already been running for some time. In some cases it would be nice to get such warnings before the script is run, just as a syntax error caused by a missing parenthesis is caught.

Are there any "static analysis" tools for R? Such a tool would not have to be perfect to be useful. Besides using undefined variables, defining variables that are never used is something I'd like to be warned about.
