Duncan,
Thank you, however, if you will look at my function (bottom of this Email message), you will see that I have used print(). It appears that the print function is not run until the entire function completes running.
John

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?

Call print, e.g.

print(x <- lm(...))
print(y <- vif(...))
etc.
