Executing a code until a new user input aborts it (readlines?)
...ut and stop the code when the
correct input was entered.
Below is an example of a function which would run an endless loop but check
in each iteration if there was a new user input which would abort it. It
does not do the right thing obviously but maybe someone can point out how
this can be done.
startSystem <- function(){
cat("Processing code, hit ENTER to stop.")
i=a=n=1
while(!is.na(n)){
a=i+a
i=i+1
n = readline("")
}
return(NULL)
}
Thanks!
