[R] Obtaining partial output from a function that does not run to completion.

[Eric]

To heck with print(), use R's debugging capabilities instead:

trace ( minBMI, browser )

Be sure to ?trace and ?browser so you can figure out how to 
interactively debug.

How can I force the function to print sequential results rather than wait for the entire function to complete before listing the functhion's output?
