[R] convergence

I don't know what your problem is, and I am far from being a specialist, but it
seems to me that in this case you often use a variable, for example 'epsilon',
which measures your "level of convergence". Then you could you use a loop which
repeats while this measure is above a certain threshold, for example :

while (epsilon > 0.0001) {
   ... repeated expressions ...
}


Hope that helps,
