Hi - I tried to get some answer before but there seems to have no one response.
My question is that I have a class like below definition:
 
setClass("DBManager", 
   representation(channel="RODBC"))
 
My purpose of the conn slot is to hold a channel to database connection which is
returned by a command like:
 
channel <- odbcConnect("DB", uid="user",
pwd="password")
 
According to RODBC documentation, this channel is supposed to have a type of
"RODBC". However, if I declare my class as above, R will complain that
it does not know about "RODBC" type or class. Please clarify. Thank
you.
