"Hello."
What the heck? Who are you, and where is the green sofa?
"That's me, I am the green sofa.
You found me... Impressive."
Well, I clicked the button that said "green sofa", and-

"Let's stop wasting time.
Do you see the URL?
You can change it to get to hidden rooms.
So let me give you the first hidden room.
Load the `iris` dataset in R, then
Change the URL to the name of the flower with the highest
mean of the length of their sepals."
And just like that, the green sofa flies off into the night...

Where do you want to go?
