R Help Trying to figure out how to create a simple program that will as the user from a value input and simply add 5 units to that value then ask the user for another value and add 45 units to it and on and on. Then how does one exit the loop of program? # Create a function called `add_five` add_five <- function(x) { # Add 5 to the input value x + 5 } readline(prompt = "Enter a number: ") Jeff [[alternative HTML version deleted]]
HI Jeff, This might give you a start. add_stuff<-function(x) { x<-xinc<-NA finished<-FALSE while(is.na(x)) x<-as.numeric(readline("What number do you want to start? ")) while(is.na(xinc) || !finished) { xinc<-as.numeric(readline("What number do you want to add? ")) if(is.numeric(xinc)) x<-x+xinc answer<-unlist(strsplit(readline("Do you want to keep doing this? (y/n) "),""))[1] finished<-toupper(answer)!="Y" } return(x) } Jim On Thu, Aug 31, 2023 at 11:46?AM Jeff Reichman <reichmanj at sbcglobal.net> wrote:> > R Help > > > > Trying to figure out how to create a simple program that will as the user > from a value input and simply add 5 units to that value then ask the user > for another value and add 45 units to it and on and on.

Add a break. Something like: If (is.character(x)) break If you have nested loops then a similar statement is needed for each level. "break" only exits the innermost loop.
