[R] how to store recursive results

[X.H Chen]

Hi Gabor,

Thanks for pointing out this for me. However, what I try to get is how to 
construct such form a function f that

ret<-f(...),

where ret contains the each recursive result from f, and meantime f consists 
of no <<- operator. Do you have any idea how to implemet this. Thanks a lot 
for your suggestions.
