[BioC] data (golub) in the CMA vignette (version 1.4.0)

[Paul Shannon]

Example 1 in the CMA vignette begins

 > data(golub)
 > golubY <- golub[, 1]
 > golubX <- as.matrix(golub[, -1])

It appears that the golub data package has been superseded by  
golubEsets (v 1.4.7).  It is not immediately clear to me how to  
extract the equivalent of golubY and golubX from the ExpressionSet.

Any advice?

Thanks!
