Hi,
I have an expressionset object:

str(exprs(mydata.eset))
  chr [1:96, 1:12] "35.7403" "32.772404" "31.26038" "45" ...
  - attr(*, "dimnames")=List of 2
   ..$ : chr [1:96] "geneA" "geneB" "geneC" "geneD" ...
   ..$ : chr [1:12] "SampleA" "SampleB" "SampleC" "SampleD" ...

The object contais 96 genes and 12 samples. How to boxplot the object
 > boxplot(exprs(mydata.eset))
Error in x[floor(d)] + x[ceiling(d)] :
   non-numeric argument to binary operator

thanks for your help.

david
