But it says


      'Expression' here is not being used in its colloquial sense, that
      of mathematical expressions.  Those are calls (see 'call') in R,
      and an R expression vector is a list of calls, typically as
      returned by 'parse'.

so it already has a link.

'Expression' was often misused in the R documentation, and a couple of months ago I tried to move to a more careful usage.
