expression matrix

Christophe -- You'll want to coerce golubMerge to an ExpressionSet.
library(Biobase)
library(golubEsets)
data(golubMerge)
golubUpdated <- as(golubMerge, "ExpressionSet")
Warning messages:
1: In asMethod(object) :
  missing or mis-shaped 'se.exprs' in original object; creating ExpressionSet without se.exprs
2: The phenoData class is deprecated, use AnnotatedDataFrame (with ExpressionSet) instead 
3: The phenoData class is deprecated, use AnnotatedDataFrame (with ExpressionSet) instead 

The warning messages above can, in this case, be ignored. After this,
everything should be fine, e.g.,
exprs <- exprs(golubUpdated)

 Hello,

 I am to run this R script but i keep getting this error.

 I tried to find information on the website but no luck. (exprSet...etc)
I think you want to try the Bioconductor (http://www.bioconductor.org)
web site instead of the R web site.
