please see here if you need to install GEOquerry library.

library(GEOquerry)
eset <- getGEO("GSE4051", getGPL = FALSE)
exprs(eset)
> exprs(eset)
Error in (function (classes, fdef, mtable)  : 
unable to find an inherited method for function ‘exprs’ for signature ‘"list"’
> pData(eset)
Error in (function (classes, fdef, mtable)  : 
unable to find an inherited method for function ‘pData’ for signature ‘"list"’

As a sanity check I wanted to see if GEOquerry was working properly and I think something is fishy.

> class(eset) == "ExpressionSet"
[1] FALSE

Also in the Environemtn window of Rstudio the eset variable is showing as a Massive list, shouldn't it be some object?
