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");
plot(1, 1, ylab = expression(var(U[list(a,b)]^(list(n,d)))),
xlab = "n", type = "l")
or if you want to replace a, b, d, and n by values, use:
a <- 1
b <- 2
d <- 3
n <- 4
plot(1, 1, ylab = substitute(var(U[list(a,b)]^(list(n,d))),
list(a=a, b=b, d=d, n=n)),
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.
Define other margins, see argument "mar" in ?par, e.g.
par(mar=c(5,5,4,1)+.1)

Thanks, in advance.
