how to store recursive results
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. Cheer Xiaohui Chen Dept. of Statistics UBC, Canada

Note that <<- is not necessarily global:
if (exists("x")) rm(x)
f <- function() {
x <- 2
g <- function() x <<- 3
g()
x
}
f() # 3
exists("x") # FALSE
