Little useless-useful R functions – Play rock-paper-scissors with your R engine

Naaah! not a joke. But quarantine restrictions are getting tighter and you might want to spent playing some useless game with your R engine, whilst programming, doing machine learning or other learning.
Without complications, the simplest version of this game is to play against R Engine. Here is how to:
##### Input bet as a function play_RPS <- function(bet) { bets <- c("R","P", "S") if(bet %in% bets){ solution_df <- data.frame(combo=c("RP", "PR", "PS", "SP", "RS", "SR", "PP", "RR", "SS"), win = c("01","10", "01","10", "10", "01", "00","00","00") ) REngine <- sample(bets,1) combo <- paste0(REngine,bet, collapse="") res <-solution_df[ which(solution_df$combo==combo),2] if (res=="10"){ print(paste0("You lost. Computer draw: ", REngine), collapse="") } else if(res=="00"){ print(paste0("It's a tie! Computer draw: ", REngine), collapse="") }else { print(paste0("You win! Computer draw: ", REngine), collapse="") } } else { print("Please input valid bet!") } }
And by running the function with your bet:
play_RPS("R")
Getting the results (in my case / run).
Game-play could use some refinement. I have decided to use x11 function, I have already mentioned it in one of my previous posts. In this case, I will be building a loop with x11 function for continuous selection of Rock-Paper-Scissors. With x11 you can get little bit better interface:
As always, the code is available at Github.
Happy R-coding! And stay healthy!
