[R] How to use curve() function without using x as the variable name inside expression?

[C W]

Hi all,

I want to graph a curve as a function of mu, not x.

Here's the R code:

x <- rnorm(10)
y <- rnorm(10)

func <- function(x, y, mu){
   x + y + mu ^ 2
}

curve(f = func(x = x, y = y, mu), from = 0, to = 10)
I know I can change variable mu to x, but is there a way to tell R that mu
is the variable of interest, not x.

Thanks in advance,

Mike
