A couple of days ago we released a package named fun to CRAN, but I did not dare to send an announcement to email@example.com as usual. This package is a collection of some classical computer games (e.g. the Mine sweeper and Five in a row) as well as other funny stuff. Some examples:
## install.packages('fun') library(fun) if (.Platform$OS.type == "windows") x11() else x11(type = "Xlib") mine_sweeper()
You can take a look at the list of functions in this package by reading the HTML help page (go to
help.start()), and I also need to mention the demos, e.g. see
demo('TurtleGraphics') for a demo of Turtle graphics (how many people know the old Logo programming language?), and
demo(package = 'fun') for a list of all demos in this package.
demo('RealTurtle', package = 'fun')
Although these topics are not new, they can still be good programming exercises.
We started writing this package more than two years ago, but it was almost forgotten later until a few days ago someone mentioned the game “Five in a row” in our web forum. This forum is almost the Chinese version of R-help, and it is not unusual for people to bring forward all kinds of funny ideas with R. If you are at useR! 2011 right now, you probably have heard from George Zhang about the Chinese R conferences these years, and this forum has been the sponsor and organizer ever since the first conference (which I initiated). However, please do not get a wrong impression that Chinese useRs are doing mine sweepers with R every day.
Feel free to share with us if you have more fun. The developers’ page is at: https://github.com/yihui/fun
P. S. This package may remind some people about the sudoku package (e.g. Joshua Wiley has noticed it), and some people may even remember this:
