Problem with R code (unit Vector).

Question

So. here is the task.
You are given a vector that contains color names.
You need to take a number as input, and output the color name at that index.

Here is my solution.
colors <- c("Red", "Green", "Blue", "Purple", "Black", "Yellow", "Orange", "Pink", "Brown", "White")
var <- readline()
var <- as.integer(var)
print(colors[var])

Could you please explain to me what is wrong with it?

Answer 1

in the examples, it shows that input should be gotten like this:

input <- readLines('stdin')

(not readline())

Answer 2

Lisa, Thank you!
I've followed this (https://www.geeksforgeeks.org/taking-input-from-user-in-r-programming/), as I could find an example in the unit.
