When I invoke the function for plotting I get a vertical line, instead of a horizontal line of unit amplitude. Numerical evaluation of the argument of the function doesn't give the expected 

Are you sure?  It likes like a vertical line because the upper limit on
the graph is one so I can't see the horizontal line.  Try
plot2d(unit_step,[x,-1,1],[y,-5,5]).

And in what way does numerical evaluation of the function not work? 
It's really hard to figure this out when all you say is it doesn't work;
we don't have ESP.
