The Tetris game in R


A poor man's implementation of the Tetris game in R. Yes, you are right again: it has nothing to do with time series decomposition, changepoint detection, and time series segmentation. Its only remote connection to Rbeast is that this is a practice script I wrote to learn R graphics for implementing Rbeast.

	tetris(height=25, width=14, speed=0.6) 



integer; number of rows of the mine grid along the vertical direction.


integer; number of columns of the mine grid along the horizontal direction.


numeric; a time interval between 0.05 and 2 seconds, specifying how fast the tetriminos moves down. The smaller, the faster.



  • Left arrow to move left.

  • Right arrow to move right.

  • Up arrow to rotate.

  • Down arrow to speed up.

  • Space key to sink to the bottom.


This function works only under the Windows OS not Linux or Mac. An interactive graphics window is needed to run this function correctly. So it won't run in RStudio's plot pane. The function will use the x11() or x11(type='Xlib') graphic device to open a pop-up window.
