This error arose because I tried to get clever with object orientated 
programming in R, and it doesn't work as I expected. I have revised the 
functions by going back to an older but simpler style and they should all 
work again.

The default values are what I would recommend.

The help document now has an example using data from the SMA package, see 
limma version 1.1.2.
