maybe we've already diskussed this before, but Kurt and I can't
remember ...

is.vector() of an one-dimensional array returns FALSE. this is also the
behavior of Splus, but totally counter-intuitive for me ... IMO an
array of dimension 1 is exactly the definition of a vector ...

it also breaks our current plot.factor, which is simply a


table() returns an one-dimensional array, but barplot only accepts
vector and matrix arguments ...

of course one could check additionally for arrays with correct
dimension ... but ...

any opinions?
