Do you need a loop at all?
Will this do the trick?

While you can build up a vector like this in a for loop, this is exactly
the sort of construction that leads to excessive memory growth because on
each iteration of the loop R creates a new copy of the vector x - old
copies have no references to them, but are not deallocated until the next

Re: [R] Creating a loop with an indefinite end term
Here are a couple of constructions that work.

you don't really need to define the length?

You might want to use a while loop instead, something like:
while(TRUE){
# Do things
# Test: if your condition has occured
if(conditionHappened) break # break will end loop.
}

Everyone,
I'm very new to R, especially when it comes to loops and functions, so
please bear with me if this is an elementary question. I cannot seem to
figure out how to construct a loop which runs a function until a certain
value is computed. For example, say I have the following:
num = numer
