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

Hello,
The following will work, but I don't know if it's what you want. func2
will get x and y from the global environment.
func2 <- function(mu){
x + y + mu ^ 2
}
curve(func2, from = 0, to = 10)
Hope this helps,
Rui Barradas

Hi Rui, Thank you for your help. That works for now, but eventually, I need to be pass in x and y. Is there a way to tell the curve() function, x is a fix vector, mu is a variable!
