[R] using RKWard for a function plot

[KAYVEN RIESE]

Is it possible to use the RKWard GUI to just plot a function?  I will have 
some exponential function, I need to plot u as a function of y where


      u    =   -2yg  exp(-y^2/beta)
                -----------------
                    f

   where everything else other than u and y are various constants.
