Dos this do what you want?
plot(1:10, xlab=expression(delta*{}^18*"O" * " VSMOW [‰]"))
The specific is to put an empty item there to hold the superscript.
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.
