Combinate 2 scripts to disable a function?

How do I conbine these 2 script and then deactivate the fire function till R is pressed?

 #pragma strict
 var bulletPrefab : Transform;
 var player : GameObject;
 var force : float = 2000;
 var shootForce : float = 1000;
  
 function Update () {
     if(Input.GetMouseButtonDown(0)){
          fire();
  
         
     }
 }
  
 function fire(){
     var instanceBullet = Instantiate(bulletPrefab,transform.position,Quaternion.identity);
         instanceBullet.rigidbody.AddForce(transform.forward*shootForce);
 }

//And then we have the deactivate script

 var Enabled : boolean;
 private var counter : int;
  
 function Start () {
 Enabled = true;
 }
  
 function Update () {
  
 if(Input.GetKeyUp(KeyCode.R)){
 Enabled = true;
 }
  
 if(Input.GetKeyUp(KeyCode.Mouse0)){
 counter += 1;
 }
  
 if(counter == 7){
 Enabled = false;
 counter = 0;
 }
  
 }
