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.
