## 3  Autoformat when xtable is created
xtable(mtcars, align = xalign(mtcars), digits = xdigits(mtcars),
       display = xdisplay(mtcars))

## equivalent shortcut
xtable(mtcars, auto = TRUE)


## 4  Autoformat existing xtable
mt <- xtable(mtcars)
align(mt) <- xalign(mt)
digits(mt) <- xdigits(mt)
display(mt) <- xdisplay(mt)

## equivalent shortcut
mt <- autoformat(mt)
