[R] Using the object of character data type as the name of the slot
Dear all, I have a character string object: > chara [1] "The name of first slot" and a list object: > class( try1) [1] "list" what I want to do is to use the chara as a slot's name of "try1". Of course I could do it like: > try1$"The name of first slot" <- matrix("", 3, 4) to create a slot of 3x4 matrix with the name "The name of first slot" However, I would like to know how could I utilize the object chara , and to use the characters it contains as the name of the slot of try1. I appreciate for any suggesion. Thanks. -- Lam C.

You can use slot(try1, chara) <- matrix("", 3, 4) as long as the slot name contained in chara really is a slot.
