Welcome to Session 2: Variables, Data Frames, and graphics

Welcome back! And if you are new, welcome! In this session we are going to get into a few more fundamental R concepts and then roll up our sleeves and get into the good stuff.

A quick recap of topic from last time

• Guided tour of RStudio (using RStudio Cloud)
• Wrote our first program in R (named 'hello world')
• Reading R code
• Recognizing functions (starts with name( )
• The role of packages

Goals for today

1. Familiarize the idea of variables and data frames
2. Explore code examples

On to the exercises
