[BioC] globaltest covariates problem

[Dario Greco]

ciao all,
my wishes for a marvelous 2006 to everybody!

i am trying to run globaltest using two covariates on a exprset (15 saples x 
22283 probesets, chipset affymetrix U133A).

here is my command:

globaltest(exprs.object, covar1 ~ covar2, cellcycle)

where:

> show(exprs.object)
Expression Set (exprSet) with
        22283 genes
        15 samples
                 phenoData object with 2 variables and 15 cases
         varLabels
                covar1: 
                covar2: 

> covar1
 [1] 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0
> covar2
 [1] 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0

> class(covar1)
[1] "numeric"
> class(covar2)
[1] "numeric"

but what i get in output is:

Error: Sample names in X inconsistent with sample names in Y.

the phenoData is ok and if i try to run GlobalAncova() everything goes 
smoothly.
where is the problem? 
thanks a lot for your kind help!

greetings
Dario
