[R] Using the object of character data type as the name of the slot

2007-06-21 Thread Alex Tsoi
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.
