[BioC] express & summary.stat=li.wong -> error report

[Hinnerk Boriss]

Hi there!

I have a statement like this: 

	data.lwf <- express(data, summary.stat=li.wong)

and I get the following error message:

	Error in data.matrix[,!phi.outliers] %*% phi[!phi.outliers] :
			non-conformable arguments

What does this error message mean in detail? Does the li.wong routine
require to do some outlier checking beforehand? If so, what method is
approporiate? Just to mention, I am not a fan of removing outliers.
Anyway, How would I find the trouble making values in my data?

Cheers,
Hinnerk
