- Update your console (I guess you are on Windows?) by using
flush.console().
- You might want to measure time consumption, hence see ?Rprof.
- Save some more time by moving as much as possible out of your loop by
doing it in a vectorized way (I don't know all the functions you are
using, hence cannot make any further recommendations).
