Is it possible that the original poster had the
Hmisc package loaded?
Hmisc::reorder.factor
function (x, v, FUN = mean, ...)
ordered(x, levels(x)[order(tapply(v, x, FUN, ...))])
<environment: namespace:Hmisc>
Without that package, reorder.default gets called:
getAnywhere('reorder.default')
A single object matching ‘reorder.default’ was found
It was found in the following places
registered S3 method for reorder from namespace stats
namespace:stats
with value
function (x, X, FUN = mean, ..., order = is.ordered(x))
{
scores <- tapply(X, x, FUN, ...)
ans <- (if (order)
ordered
else factor)(x, levels = names(sort(scores)))
attr(ans, "scores") <- scores
ans
}
<environment: namespace:stats>

Or at least is seems that way to me. It's not a big problem, but the
behavior doesn't match the documentation. (I think r-help is the
place to report this. )
