You *can* do it with
myname=function(dat,x=5,y=6){
name<-paste(deparse(substitute(dat)),"res",sep=".")
assign(name, x+y-dat, parent.frame(), inherits=TRUE)
}
but I would be very surprised if this is actually the best way to do
whatever complex thing you are really doing.
It's very unusual for assignments into the global workspace to be a
useful R programming technique.
