Is this what you would expect to have. Definitely you can make this function
more elegant:
fn1 <- function(x = 10) {
cat("Please type the option number to get your Y value:\n\n")
cat(" 1. Y = 1.\n
2. Y = 2.\n
3. Use the default y.\n
4. Choose my own value for y.\n\n")
opt=scan

Have you tried scan()?:

1: 2
2:
Read 1 item

Dear all, I am looking for some procedure to send inputs to a function
interactively. Here is an example:
fn1 <- function(x = 10) {
y <- 0
# ask user whether he wants to put some other value for "y"
# R will show 2 options: 1. y = 2
# 2. y = 3
# user will choose ei
