SLIDE 24
Challenges Opportunities
Why should you use R?
Because you want to do more Because you can create a better scientific workflow
SLIDE 25
Challenges Opportunities
Why is R better for science?
R will always be here Scripting Reproducible research tools
Scripting Report generation Data sharing
SLIDE 26
Challenges Opportunities
Reproducible Research
All data and replication code is public All results come directly from code Analysis is about writing a script, not pointing and clicking Makes changes and collaboration easier
SLIDE 27
Challenges Opportunities
Scientific Workflow
Store data in perpetually readable formats Write a complete analysis script Script should run analysis and output results Reports should import results directly Share data, script, and codebooks
