@stephpenn1 what about

1. Brief review - data processing in base R versus dplyr

   • Split-apply-combine review using Orange

2. Data joins (merges) using dplyr

   • White-board left_join versus others
   • Practice joining x and y

3. Functions

   • How to write
   • Parameters and return values
   • Exercise: write timestwo()
   • Locals versus globals; how does find 'find' names we use? Benefit of ONLY using locals
   • Exercise: write remainder()

4. Exerises

   • Write a function to join Lillie's SLA data with the inventory data
   • Plot area per leaf by species
