## 8.3 Concepts: Rendering

• Enter/exist simply make appear things (we may want to have more control!)
• Gganimate’s animation model
• Dimensionless in same way as ggplot2 describe plots independent of the final width and height of the plot
• → final number of frames and frame-rate are only given when you ask gganimate to render animation
• Printing animation object using animate() function uses default arguments
• nframes: The number of frames to render (default 100)
• fps: The framerate of the animation in frames/sec (default 10)
• dev: The device to use for rendering the single frames (defaults to ‘png’)
• renderer: sets the function used to combine each frame into an animate (defaults to gifski_renderer()39)
• → if you displike defaults change argument in animate() directly
• animate(): Animation function that returns the result of the renderer

1. In principle you can switch between different renderers such as gifski.
