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

[Rui Barradas]

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
