I think slot() is only necessary in the case where you have a <- "myslot" slot(object, a)
which is equivalent to [EMAIL PROTECTED] It seems unlikely that you would use slot() during interactive use, but perhaps more so in programming. Even still, I rather infrequently find the need for slot() because classes have defined slot names---if you're going to access a slot, just use the name that you gave it in the class definition since that doesn't change from instance to instance. -roger Sebastian P.
