Adding dash-lines in R tables

Seems strange that the ascii.interger function doesn't set the  
digits argument to 0:

ascii.integer
ascii(as.integer(c(3,4,5)))
|=====================
| 3.00 | 4.00 | 5.00
|=====================

ascii(as.integer(c(3,4,5)), digits=0)
|============
| 3 | 4 | 5
|============

I should have added that I do appreciate your drawing this package to  
our attention, since it seems to have a large number of supported  
classes which should make it very useful.

Two questions:

  I am hoping there might be parameters that could be set so that a  
more "mathematical" version of matrix-class might be produced:

| 1.00  3.00 |
| 2.00  4.00 |

Rather than:

|==============
| 1.00 | 3.00
| 2.00 | 4.00
|==============

I see by running the help examples in print.ascii that some  
standardized type arguments have been designed. Where should I look to  
see how to design other user-defined types? IAfter looking at the  
help(package=ascii) and help() for several of the functions I am  
guessing that I might find that asciidoc is a format that is elsewhere  
described?
