Re: [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.

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

Hi all,

How to store recursive resutls from a function for each step without using
global operators <<-? Thanks ahead.
