[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.

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