Today's Goal
- Understand reproducibility and version control
- Comfortably navigate RStudio fundamentals
- Be able to define common terms including: data frame, function, variable, package
- Interact with Git from RStudio (committing and pushing)
- Use a few functions, including:
glimpse(),group_by(),summarize(), andfilter() - Understand the pipe operator
%>% - Create a reproducible report via today's application exercise using R Markdown
Quiz
Q - What is a reproducible data analysis?
Near-term goals:
- Exact/similar tables and figures can be generated from the code and data
- The code performs an intended task
- Purpose of the analysis is clear
Long-term goals:
- The code can be used for other data
- The code can be extended to do other things
Quiz
Q - What is difference between R vs. RStudio?
R:
- Open-source statistical programming language
- Easily extensible with packages, collections of reproducible R code
RStudio:
- Convenient interface for R called Integrated development environment (IDE)

Q - What can you do with R Markdown?
- Create fully reproducible reports with code for analysis and text for narrative
- Every assignment as an R Markdown document (with
.Rmdextension) - R Markdown document should be complete in itself. The environment of your R Markdown document is separate from the R Console!

Q - Why is it important?
- Otherwise you lose track of your work and become clueless where to go back when you need to fix things! e.g. final.docx, final2.docx, final_final.docx, final_final_XXXX.docx, ...
- At each version, important to leave an informative tag
