Look at the replicate function, it takes an expression (does not need a function) and runs that expression the specified number of times. Will that accomplish what you want without needing to worry about substitute, quote, eval, etc.?
Yes, this is very similar to what I want to achieve. One of the main differences is that 'replicate' builds up a list of all call results, and for my measurements I want to avoid the resulting (time and memory) overhead. But I did look at the implementation of 'replicate' and this is where I took the trick of using eval.parent and substitute from. All the best, Jochen
