I am downloading data from ArrayExpress using the R package "ArrayExpress":

    savedir='C:/myDIR'  
    myAE=getAE("E-MTAB-797", type = "raw", path = savedir)
    eset=ae2bioc(mageFiles = myAE)

However, I get an error:

    Error in as.character.default(<S4 object of class "ExpressionFeatureSet">) :
    no method for coercing this S4 class to a vector
    Calls: DLfunction ... eval -> .Method -> as.character -> as.character.default
    Execution halted

What am I doing wrong? Thanks in advance
