The addBBands function returns a silent chobTA object which can be accessed using attr:

x=addBBands()
bands=attr(x,"TA.values")

I'd assume the dn and up columns correspond to the bands.

If you look at the source code for addBBands(), you'll see that it calls BBands. Try this:

BBands(HLC(stock))
