True, it doesn't say that. As you say, ?plot.stepfun says
> xlim,ylim: numeric(2) each; range of 'x' or 'y' values to use....
and ?plot.window says
xlim, ylim: numeric vectors of length 2, giving the x and y
coordinates [sic] ranges.
...both of which are rather vague, not saying what the *effect* of
these "ranges" is. Perhaps a more precise description would be:
xlim, ylim: each is numeric(2) and defines the range of the x and
y scales. cf. xaxs; xpd.
More experienced users can perhaps come up with better language.
