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
barplot(table(x))
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?

R-alpha: is.vector of one-dimensional array

I assume by "one-dimensional array" you mean a two or higher dimensional array with all but one of the values from dim(x) being 1. This is possibly counter-intuitive, but there are cases where one needs to distinguish these. Perhaps length(dim(x)) would be better, but dim returns NULL for a vector. This is even more counter-intuitive to me. I think it should return length(x) for a vector. In any case there is lots of code out there that will break if you change these.
