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)
}

Re: [R] How to create an R input
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.

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: ")
