Something is missing; this last sentence of yours appears to be not
complete, does it?
Regarding Uwe's remark and Peter's nice aesthetic suggestion:
> plot( 1, 1, xlab = substitute( Z[list(~i, j)], list( i = 1, j = 2)))
should solve both "problems".
This does work even in R as old as 2.7.1 (and, of course, for a more
recent version as Uwe already stated).
