第一个模拟，可能并没有模拟出完全随机均匀地扔针，或者计数有瑕疵？
扔了400次，偏差应该不会那么大吧
My bad, 高估了扔火柴的效率, 看到过wikipedia上面有个例子扔17次, π就估计到了3.1

Yihui, thank you for these great examples. I am trying to understand how I can use the animation package to build animations that cumulate/preserve old frames rather that overwrite. Each of the 3 plots in your buffoon.needle example cumulate frames in that sense. I would greatly appreciate your advice. Please note, I also posted essentially the same question, but with a few more details, here: https://stackoverflow.com/questions/64997085/how-to-cumulate-preserve-old-frames-using-the-animation-package

Is it possible to embed in pdf using r markdown a video made with the animation package? I couldn't find any such example anywhere, SO included.
