Remove delay from start of animation

This is for animating a chart. I am using plotly in R, but it seems likely I would see the same behavior in other environments.

When the plot is not playing and positioned at the first frame, the start of animation is delayed by the frame specification in the animation options. For example, if frame is set to 2000, there is a two second delay before things start to move.

Is there a setting that removes the delay without affecting subsequent times?
