[R] Reducing dimension of a list object

Hi all, I generally use the Reduce() function to reduce the dimension of list object. However in my current session I have few objects which are actually list of list of list..(say n step). If I reduce their dimension then I have call Reduce() function many times. Therefore my question is, is there any 1-step way to reduce the dimension at the lowest level? Take this example:  

lis1 <- list(4)

lis2 <- list(1,8)

lis3 <- list(lis1, lis2)  

# Now I want to reduce the dimension of lis3 to a column vector:  

> Reduce("c", Reduce("c", lis3))

[1] 4 1 8  

I want to have some mechanism so that I need not to call reduce() function twice. Is there any way to do that?  

Thanks and regards,
