i want to know how to write R script that takes from the user a list of numbers and outputs the following of the list:

1. Mean and median.
2. Standard deviation and range.

i want it to receive any input data from the keyboard and display data on the screen.

here the script that i used :

num <- readline (prompt = "list of numbers")

num <- as.numeric(num)

result.mean <- mean(num)

print (result.mean)

result.median <- median(num)

print(result.median)

result.sd <- sd(num)

print(result.sd)


but it didnt work and i'm sorry if the script not in correct format but i dont know how to display it .

It only works for a single number input, if you wish to accept multiple numbers separated with comma or space, we need so split it on delimiter before converting to numeric. See related StackOverflow post:
