How do I index referenceClass objects?

So trying to use referenceClasses for the first time. I figured out how to create an object, but I want an "array" of objects. I usually use data.frames but you can't put an object in a data frame. trying to use lists, but can't figure it out. Like this:

Stock <- setRefClass("Stock",
    fields = list(      
        symbol = "character",
        expArray = "data.frame",
        quote = "numeric",
        ))

to create an object:

validExp <-c("131108","131115","131122","131129","131206","131221","140118","140719","150117")
validStocks <- c("AAPL", "TSLA","GOOG","HLF")

expArray <- data.frame(exp = validExp)
aStock <- Stock(symbol = "GOOG", expArray = expArray, quote=0)

which works fine. But now how to I get an "array" of Stock objects indexed by validStocks?

I'm having a hard time trying to figure out exactly what you want, for example, what does:

expArray = expArray = expArray

mean? If you want an "array" of valid stocks, why not just create a list of reference objects

l = list(4)
l[["AAPL"]] = aStock
