[R] Pass an equation as an argument of a sub-function

[Frank S.]

Dear all,

I have defined an R function g(y) wich in turn is inside other R function f(x). The function g(y) depends on an
equation, and I would like to know if such an equation could be passed as an argument of the main function
(taking into account that we should change the variable "x" to "y").
As an example, I have:

function(x) {         # Main function, called f(x)

  -----  (code)

  function(y) {        # Sub-function, called g(y)
    -----  (code)
    eq <- y^2 -3*y
    ----- (code)
  }

  ----- (code)

}

In summary, I would like to know is there is any way to:
Put the equation "eq" as an argument of the main function f(x).


Thank you very much!

Frank
