[BioC] LIMMA: Suitable measure of error from result object. stdev.unscaled?

[Daniel Brewer]

Hello,

I have a 2-colour microarray experiment with a complex design.  I would
like to visualise the estimated coefficients and associated error with
the most significant genes that come out as result of LIMMA (lmfit,
contrasts.fit, eBayes).  I thought that it should be stdev.unscaled, but
this seems to be the same for all the genes, which I don't think makes
much sense.  What is an appropriate way to calculate the estimated error
associated with a coefficient?

Many thanks

Dan
