Hi
I have following piece of code:
--------------------------------------------------------------------------------------------------------
In[1]:=BifurcationDiagram[f_, {r_, rmin_, rmax_, rstep_}, {x_, x0_},
start_,
         combine_] :=
	Module[{R, temp, MapFunction},
		R = Table[r, {r, rmin, rmax, rstep}]; (* The range
    of values of the parameter *)
		MapFunction = MakeMapFunction[{r, x}, f];(*
        Construct the iterating function *)
		temp = Nest[MapFunction[R, #] &, x0 + 0.R, start + 1];(* Starting
iterates \
*)
		temp = NestList[MapFunction[R, #] &, temp, combine - 1];(*
Subsequent \
iterates *)
		temp = Map[ Union, Transpose[
          temp] ]; (* Remove duplicate values from cycles *)
		Flatten[ MapThread[Thread[{#1, #2}] &, {R, temp}], 1]
	];

In[2]:=ListPlot[BifurcationDiagram[(1 - r) x + (r(2858.16)/(x - 500)
^0.82) - 30000r, \
{r, 0.1, .2, .0001}, {x, 600}, 10000, 100], PlotStyle ->
        AbsolutePointSize[0.0001]];
------------------------------------------------------
The following errors are produced:
Graphics:: gptn : Coordiantes -30000.5+0.0169522 i {0.1,
-30000.5+0.0169522 i }....is not a floating pont. Is there any
possible solution to this problem ?
Best regards.
