normal_areas_movie(starting_multiple = 1, delta_multiple = 1,
  ndec = 3)

Arguments

starting_multiple	A non-negative numeric scalar. The value of the multiple used in the first plot.
delta_multiple	A numeric scalar. The amount by which the value of the multiple is increased/decreased after one click of the +/- button.
ndec	The number of decimal places to which to round the probability that is superimposed on the plot.
