I do not think that is necessary:

plot(1:10, xlab=expression(delta^18*O~VSMOW[""]))

(I wasn't sure if the [.] operation was supposed to be a subscript.)

I generally avoid spaces in plotmath expressions and use tildes "~" to accomplish any needed spaces. The asterisk "*" is the non-spacing separator between elements.
