Using EasyJoystick in lieu of Input.GetAxis

I'm trying to use EasyJoystick instead of the Input.GetAxis but for two days haven't found any answers. The code below I would like to control the player with the joystick.

 public void Handle (Transform target)
     {
         if (Input.GetKey (KeyCode.LeftAlt) || Input.GetKey (KeyCode.RightAlt) || Input.GetKey (KeyCode.AltGr)) {
             Screen.lockCursor = false;
             Screen.showCursor = true;    
             return;
         } else {
             Screen.lockCursor = true;
             Screen.showCursor = false;
         }
         if (axes == RotationAxes.MouseXAndY) {
             rotationY += Input.GetAxis ("Mouse Y") * sensitivityY;
             rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);
             
             target.localEulerAngles = new Vector3 (-rotationY, target.localEulerAngles.y, 0);
             target.Rotate (0, Input.GetAxis ("Mouse X") * sensitivityX, 0);
             
         } else if (axes == RotationAxes.MouseX) {
             target.Rotate (0, Input.GetAxis ("Mouse X") * sensitivityX, 0);
         } else {
             rotationY += Input.GetAxis ("Mouse Y") * sensitivityY;
             rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);
             
             mCamera.localEulerAngles = new Vector3 (-rotationY, mCamera.localEulerAngles.y, 0);
         }
     }
 }

I have added to the head of the class

 public EasyJoystick joystickR;

and added it to inspector in the script

I changed

  if (axes == RotationAxes.MouseXAndY) {
             rotationY += Input.GetAxis ("Mouse Y") * sensitivityY;
             rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);

to

  if (axes == RotationAxes.MouseXAndY) {
             rotationY += joystickR.JoystickAxis.y * sensitivityY;
             rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);

but continue to receive errors: error CS0103: The name `joystickR' does not exist in the current context
