האקתון R מחירי רשתות השיווק ב-4 לאוגוסט (יום ג') בין 18:00 בערב ועד ל- 22:00

The purpose of this meeting is to introduce ourselves to each other, the data and of course R.

From the response to the sign up form people have filled out thus far there are quiet a few fields interested in attending: statistics, computer science, geography, advertising, and more…

Each participant will receive a PDF containing the meta description of the files and a sample of the data retrieved thus far. After we are all on the same page we will split into groups that will have a task to do that serve the overall goal of understanding the data and getting it ready for any future research.
