Jan. 9Jan. 13Go to www.r-project.org and install R on your computer (or a friend's computer). Once it's installed, start it up and type the following command at the prompt (by the way, I updated this so it works on any type of machine!):
as.numeric(format(Sys.time(),"%j%S%M%H"))

Be sure to type this exactly (R is case-sensitive). You'll get a 7- or 8-digit integer as a response. Email this integer (nothing else) to dhunter@stat.psu.edu from your psu.edu account with the subject "Jan. 16 assignment".
