Try this one:

input <- readLines('stdin')
x <- as.integer(input[1])
y <- as.integer(input[2])
z <- as.integer(input[3])

print(max(x, y, z))

Answer 6

I did all the the project from the R course and i had the green message for each project. But in the main page (of R course), it is like i did none. For exemple in the first project (The greatest number), this my code :

input <- readLines('stdin')
x <- as.integer(input[1])
y <- as.integer(input[2])
z <- as.integer(input[3])

print(max(x,y,z))

When I run it, I get the green message but in the main page it's stay blue with the 8/9. My answer is not recorded i don't know why.

It is the same for all the project of the R course.
