I'm having the same problem you are, but I noticed that on the mobile app everything is good, and that if I go to my list of certificates on the web it's available.

Tabi Mehdi 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))

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.
