rbind and data.frame

[...]

My real problem is how to create a data frame in a sequentially growing
manner, when I know the final size (no of cases). I want to avoid to
call 'rbind' many times, and instead create an 'empty' data frame in
one call, and then fill it. Are there better ways of doing this?

Got no answer to this one, so I provide one myself:

The answer is: Yes, definitely. I did this, with pure  R  code, and 
created a new data frame with around 58000 records. It took 7 hours to 
run. I then did it with compiled code (Fortran), and that made a slight
difference:  It took 4.8 seconds(!).
