UDP and TCP are entirely different worlds. They don't share the same
port space; TCP port 9000 and UDP port 9000 are different things. Plus,
UDP is connectionless, so you can't "connect" to a UDP port. All you
can do is throw packets at a server, which may or may not be listening
for those packets.
You will either have to rely on an external program to do the UDP
communication for you, or write an extension to R to provide this
functionality.
Suitable helper programs are 'nc' and 'ncat'. nc is abandonware, so the
nmap folk built their own version of the same idea and added it to nmap
v5. nmap v5 is very new, though, so you might have nc on your system
already, but and old version of nmap, and prefer to use the defunct
program rather than upgrade your nmap.
