R help - Oct 2008 - Print call condensely

Hello all,

I want to print out "call" from my function. When I have  a long list
of
arguments or long names for them, I either got mulilines using default 
print or big blank space using cat:

foo<- function(data, newdata)
{
   call <- match.call();
   cat("Call:\n");
   print(call);

   cat("\nCall:\n", deparse(call), "\n\n", fill=TRUE,
sep="")
   cat("\nCall:\n", gsub("\t", " ",
deparse(call)), "\n\n", sep="")

}
> foo(data=A, newdata=alooooooooooooooooooooooooooooooooongname[,5:10])
Call:
foo(data = A, newdata = alooooooooooooooooooooooooooooooooongname[,
     5:10])

Call:
foo(data = A, newdata = alooooooooooooooooooooooooooooooooongname[,     5:10])



Call:
foo(data = A, newdata = alooooooooooooooooooooooooooooooooongname[,     5:10])



Note the big space between , and 5.

print.lm behaves simimarly.


Is there any way to cat such a call wihtout the big space?


Thanks a lot.
