An stubborn error in limma

[wbb1813]

Hi guys,

I met an error when I use limma:

"Error in dimnames(fit$cov.coefficients) <-list(coef.names[est],coef.names[est]) :
attempt to set an attribute on NULL"

How can I solve it? Thank you!

You'll need to show us the command you issued the produced the error (and likely a few commands before that). I should not that it's unlikely that fit$cov.coefficients needs anything other than row.names.
