Objective
• To teach the basic knowledge necessary to use
R independently, thus helping participants
initiate their own process of learning the
specific tools needed for their research.
Logistics
• 3 days, 2 sessions each day: 8:00 am to noon and
2:00 pm to 5:00 pm
• Limited Wifi access, no internet cable connections
