[BioC] GSE states

[Lina Thomas [guest]]

I am trying to work with GSE expression data from GEO in R using GEOquery.

I am using the following commands
gset <- getGEO("GSE52",GSEMatrix =TRUE,)
ex <- exprs(gset[[1]])

But I have no idea how to separate the data in two different states. I am trying to locate states data using

varLabels(gset[[1]]@phenoData), when GSEMatrix =TRUE

or

Meta (gse), when GSEMatrix =FALSE

But I still have no clue. I need to do this for around 1000 different database, so I cannot do it using GEO2R manually... Is there a particular field I can consider state?

I also would like to know I can find out if data is already log2 transformed or log10 or inits raw form using just R.
