    Douglas> i.e.

i.e.,
   write.delim <- function(x, file, ...) 
		    write.table(x, file, sep = "\t", row.names=FALSE, ...)

So, why don't you just add that one line to your .Rprofile ?

In general, I don't think that it's worth to introduce a whole
new function just because of some frequent argument use of an
already existing function  {{and I have wondered if it was worth
to provide write.csv() at all - although, there the difference to default
write.table() is quite a bit larger}}
