tetris: The Tetris game in R

Description

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

Usage

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

Arguments

height

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

width

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

speed

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

Value

Instructions:

• 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.
