Dear All, Can anybody tell me the syntax for "User input from keyboard" in R. I mean to say that if I run the program it should ask "Please enter the date" at the begining of the program. I am using R-2.2.1 for windows. Any help will be greatly appreciated. thanks in advance. Regards, Chiya [[alternative HTML version deleted]]
Hi
cat("\n","Enter x","\n") # prompt
y<-scan(n=1)
prompts for user imput and scans 1 line from console.
