Hi, 
I was trying to have a graph whose axes are of the following type:

X axis: n and Y axis: var[U ((a,b) in suffix, and (n,d) in the power)]. 

U ((a,b) in suffix, and (n,d) in the power)-        U^(n,d) _ (a,b).
Actually I require many plots involving different values of a,b,n,d, so need to keep this complicated notation. 


The code I used:

plot(n, hn$h_pg,  ylab=expression(Var(U[2%,%1]^(n%,%0))-Var(U[1%,%1]^(n%,%0))), xlab="n",type="l");

The expression() didn't work out for this case. Can anyone help me out. 

Also due to the size of the expression in the Y axis, I want to shift the graph in the R Graphics window, so that the Y labels are also fully visible. i don't know such command which will shift the whole graph a little in the  Graphics window.

Thanks, in advance.
Shant
