Strange,

this works for me in all the Lisp versions I have:

f(x):=1/(1+x)$

E(f,x,n,a,b):=block(if x=b then return(f(b))
     else
     for i:1 thru n do if (x < a+i*(b-a)/n) then return(f(a+(i-1)/n))
);

g(x):=E(f,x,10,0,1)$

plot2d([f,g], [x,0,1]);

What version of Maxima are you using? what operating system and what 
Lisp flavor? I assume you are using Wxmaxima?
