[R] union empty set with an element

[Ragia Ibrahim]

many thanks for replying
the code 
A is list of sets where each list element is a set
 i<-1
A[i]<-3
#inside the loop
     i<-i+1;
     # for example  new element in the list will be {7,9}, each added separately inside the loop 
       A[i]  <- union( A[[i]]   ,new element)

many thanks for replying
