Passing a script as a parameter to RGui

I was wondering if it is possible to pass parameters to RGui from the command line in Windows. I would like to do something like

RGui myScript.r param1 param2

just as I would do with RScript, but I need to display a graphical interface.

Here is more information about my needs. I want to insert gui written in R in my C # forms application. What would happen, I press a button in the form, and the application starts a process that calls RGui with my script and some parameters. So far this has worked well with RScript, but now that I am showing the graphics, I need R to be interactive. Here is the code I'm using:

        myProcess.StartInfo.FileName =Pathing.GetUNCPath( r_path) + "\\Rscript";
        string script_path=Directory.GetParent(AppDomain.CurrentDomain.BaseDirectory).Parent.Parent.Parent.FullName.ToString();
        myProcess.StartInfo.Arguments = Pathing.GetUNCPath(script_path) + "\\display.r " + data_path;
        myProcess.StartInfo.UseShellExecute = true;           
        myProcess.Start();
        myProcess.WaitForExit();
