Hello!

I want analysis GSE on ExpressionSet format and I need to understand that my samples in this GSE are normalized or not. but I don't know how I recall this information( are normalized or not, and normalization method) in R Consol. Please recommend a way(code) that I can find this information in r.

Thank you.

Probably the easiest way would be to use plotDensities from the limma package. What the plot looks like will be dependent on the normalization method used, but in general if the data are normalized, all the densities will be pretty much on top of each other.
