HiI have a class which would like to hold
a connection to ODBC data connection. The handle to the connection is
something like (according to RODBC manual):channel =
odbcConnect("DSN",uid="user",pwd="password")However, I would like to
make a slot of my "foo" class to hold this object. For
example:setClass("foo", representation(channel="RODBC"))But this won't
compile as it keeps saying that it cannot find "RODBC" as a valid class
name even I have the package loaded in place. And from what I found in
RODBC manual, the 'channel' variable should be of type 'RODBC'. This
makes it even more difficult when I try define this database connection
like 'channel' above as method signature.For example, I have a class
for method like this.setMethod("setConn", "foo",  
signature(object="foo",newconn="RODBC")   function(object, newconn) {  
... do something here.   })This doesn't compile. It will keep saying
that it doesn't know about type "RODBC". Please let me know how we can
solve this? Thank you.- adschai
