[R] Remove names and more from list with capture.output()

[Sverre Stausland]

Thanks David - this is pretty close to what I am looking for. However,
the output of vec[2] now includes the row number [1] and quotations
marks at the endpoints of the row. Is there an easy way to exclude
those?

Thanks
Sverre
