Ben, I clicked on the 'here' link and was curious if any changes I made would be saved when I signed out. So I closed the "Welcome.R" script and when I signed back in it was still closed.
So, be forewarned everybody! Any changes you make will be saved for everyone else to see.
Thought I'd have a little fun with that. The Birthday Problem!
I started a Visitors.R script that creates a matrix called Birthdays: names in the first column, birthdays — month and day — in column 2. I put myself in twice so you can see how some R users punctuate when a variable number of multiple rows is possible. Starting a row with a comma looks weird but works great.
Add your name then source the whole script to see how many visitors it will take until we find a duplicate. Don't forget to hit save.
