Dear group 
I have some thing like the following code...
##start
my_list (global object)

function 1
{
list1<-mylist

function2(list1)
function3(list1)
function4(list1)
}

function2(list1)
{
assign values via <<- to the object items
}

function3(list1)
{
assign values via <<- to the object items
}
# end


why after finishing each function the object variable is NULL..how can i keep its values across functions.

Regardes
RAE
