The Minesweeper game in R

Description

A poor man's implementation of the minesweeper game in R. Yes, you are right: 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.

Usage

	minesweeper(height=15, width=12, prob=0.1) 

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.

prob

numeric; a fraction between 0 and 1 to specify the probability of mine occurrence in the mine grid.

Value

Instructions:

  • LEFT-click to clear a spot.

  • RIGHT-click to flag a spot.

  • MIDDLE-click(wheel) a cleared and numbered spot to open neighbor spots, if flagged correctly.

  • Click Restart for a new game

Note

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.
