Hi Team,

         Can you please tell me the rules of assignment in R, by value or by reference.

>From my about 3 months of experience of part time job of R, it seems most times it is by value, especially in function parameter and return values assignment; and it is by reference when referencing container sub-objects of container objects, such as elements of List objects and row/column objects of DataFrame objectes; but it is by value when referencing the smallest unit of element of a container object, such as cell of data frame objects.
