Hi Martin,
Thanks for looking into this & I can of course provide you my simple package which reproduces the error too.
i've tried contacting the lumi authors in the past and got crickets, but i'll keep trying!
cheers,
Mark

Someone will eventually load your package and wonder why sampleNames<- is behaving differently. If you think the method has an error (which I'm inferring from your documentation string), then much better to contact the packageDescription("lumi")$Maintainer and introduce the fix at the source. Or to define and use a new generic.
