new version of print.factor
Here's what S-plus 6.0 does with abbreviate.arg:
# S-plus 6.0
> print(factor(c("fooooooo","baaaaaar")))
[1] fooooooo baaaaaar
> print(factor(c("fooooooo","baaaaaar")), quote=T)
[1] "fooooooo" "baaaaaar"
Levels:
[1] "baaaaaar" "fooooooo"
> print(factor(c("fooooooo","baaaaaar")),abbreviate.arg=T, quote=T)
fooooooo baaaaaar
"fooo" "baar"
Levels:
[1] "baar" "fooo"
(The function below does not abbreviate vector contents when given
abbreviate.arg==TRUE, which may be more or less suitable depending on the
task at hand. Also, S-plus doesn't print levels unless quote==TRUE or "If
some of the levels in a factor object are not in represented in the
object", but this difference was already present in the R.1.5.0 version of
print.factor.)

Thanks to Tony Plate for letting me know what the abbreviate.arg
option does. I think this could be made more flexible (I.e.
=TRUE, =FALSE, =#, where # would be passed to the abbreviate
min.length argument). But it follows the example I was given.
"print.factor" <-
function (x, quote = FALSE, max.levels=5, print.levels = {if
(max.levels==0) FALSE else TRUE}, abbreviate.arg=FALSE, ...)
{
if (length(x) <= 0)
cat("factor(0)\n")
else print(as.character(x), quote = quote, ...)
if (print.levels) {
if (abbreviate.arg) {
cat("Levels: ", paste(abbreviate(levels(x)[1:max.levels]),
collapse = " "), "\n")
} else {
cat("Levels: ", paste(levels(x)[1:max.levels],
collapse = " "), "\n")
}
}
invisible(x)
}
It definitely could be cleaned up a bit more.
best,
