Life function

Game of Life

Conway's Game of Life

Life(n.rows=40, n.cols=40, n.cycles=100, sleep.time=0.12,
 cols=c("#f0f0f0", "#2f81c1"), random=TRUE, rnd.threshold=0.3)

Arguments

• n.rows: Number of rows
• n.cols: Number of columns
• n.cycles: Number of cycles
• sleep.time: Time for pause after each cycle
• cols: Main colors
• random: If FALSE, runs in the interactive mode
• rnd.threshold: 0 empty board; 1 all squares are filled

Details

In the interactive mode (random=FALSE), left click to define or remove cells, then click on red square in the bottom left corner to start cycles. Click positions are rounded so they are not always precise.

To stop cycles, use Ctrl-C (Linux, macOS) or Esc (Windows) in the main R window.

The code was inspired by the Github gist (which is not available anymore) attributed to Vadim Vinichenko. Note that margins influence the behavior of cells, i.e., the field is not infinite as in the "classic" Game of Life.
