I think you misunderstand what barchart does. It expects a formula, not a
named vector, as its first argument.
nm <- names(T3)
z <- factor(nm, levels=nm)

Dear Hiroto,
The anova() function reports a sequential analysis of variance, so the test
for Cond ignores the covariate. A good guess is that the effect of Cond
isn't significant controlling for the covariate. You could instead use
drop1() or Anova() in the car package.
I hope that this helps,

Dear Simon,
One doesn't generally use cbind.data.frame() directly, but rather through
the generic function cbind(). I believe that the following will give you
what you want:

cbind(fac, as.data.frame(mat))
where mat is the matrix.

The function "poly" produces orthogonal polynomials, and those
depend on the exact combinations of levels of X in "d". Consider the

In the absence of a function that will estimate a joint AR-GARCH
