[BioC] Unable to find an inherited method for function ‘exprs’

[Wolfgang Huber]

Dear Dave

this is actually not an error. The function 'exprs' expects and argument, and since you are giving it none, it complains, and one should not blame it for that. 

Perhaps can you tell us what you want to achieve, then it should be easier to help!

	Best wishes
	Wolfgang
