[R] Recursion Limits?

[Brett Magill]

See the code below.

First, what are recursion limits in R.  The function is stopping after 25 iterations for me.  Is this general, or localized?  Can recursion limits be changed?

Second, which is generally more efficient, recursion or looping over a function?

   ifelse(n<50, {print(n); n=n+1; Recall(n)}, print (n) )

Error in ifelse(n < 50, { : evaluation is nested too deeply: infinite recursion?
