When I ran this code: " x<-sample(1:5,1000000000,TRUE,c(0.1,0.2,0.4,0.2,0.1)) print(table(x)/1000000000) plot(table(x)/1000000000,type="h",xlab="x",ylab="P(x)") " My laptop was frozen and didn't respond. Although I used ctrl+alt+del to terminate r program, my laptop still did nothing. And I must restart my laptop immediately or my laptop might be broken down. Thus, I think in the future the program should have something to control the memory and time when it is running and can be terminated if necessary.
