[R] Writing to a UDP server from R?

[Saptarshi Guha]

Hello,
I have used socketConnection to connect to a TCP server. I havent
figured out a way to do the same with a UDP server.
i.e I have a server listening on 9000, communicating via UDP. I would
like to , from R, send packets to this server,

This does not work
 u <-  socketConnection('localhost',9000)
Error in socketConnection("localhost", 9000, blocking = F) :
  cannot open the connection
In addition: Warning message:
In socketConnection("localhost", 9000, blocking = F) :
  localhost:9000 cannot be opened


I have confirmed that something is indeed listening on the other side.
Any help would be appreciated.
Regards
Saptarshi
