Hi Brad, Some of the debugging functions may be of use. You can look at trace() or setBreakpoint(). But I believe Bert is correct in saying your concept of a "Line Number" and R's concept of a "Line Number" will differ.
Finally, you can look at the function findLineNum(), which can be called external to your source code file (not embedded as in your example). >?debug HTH, Bill William J.
