A review of where we are so far
Picking up from last class
- Projects and package set-up
- git / GitHub
  - syncing, commit, push, pull, branching, merging

So far…

We should know:
- Key concepts/tools of reproducibility and why we use them
- How to set up R package project with git VCS
  - More on package structures: see here
- Where your library lives
- What the key ingredients in a package are
- How to keep project synced between local and remote repos
- How to document functions
What we might not know (about packages):
- data folder and lazy loads
- inst folder and how to get at it

Our Branching Model

Merging

Git exercises (1)

Open your personal R repo (e.g. mjc346 in RStudio)
Create a new branch, test_merge. You can create this branch in the Git tab, or in Terminal, using git checkout -b test_merge
With the new branch active, create a new file test_function within the R folder. Create a simple function that takes a number x as an input, and prints “x is my favorite number!”. Save and commit this file in the new branch.
Switch back to the main branch. You should see a pop-up message. What happens to the test_function.R file? Can you see it in your file explorer?
merge the new file to the main branch using the command git merge test_merge in Terminal. What happens?
The merge command automatically merges and commits changes to the main branch

Git exercises (2)

In the test_merge branch, open the Description file. Update the version to 0.0.2. Save and commit.
Switch to the main branch. Add a second author in the Author line. Save and commit.
Now test merging the change from test_merge to main using git merge test_merge. Does this work?

Git exercises (3)

In the test_merge branch, add a third fictional author. Save and commit.
Switch to the main branch. Again add a third author, but use a different author than in the test_merge branch.
Now test merging the change from test_merge to main using git merge test_merge. Does this work?
Open the Description file. What does it look like?
After you are done, delete the branch using git branch -D test_merge
Update the Description file in the main branch by pasting the text you saved. Save and commit.

Search Engine Science

Sometimes you just need the error message

Search Engine Science

Sometimes you need to search

Package functions

install.packages : installs binary packages from CRAN
devtools::install_github: installs from Github
devtools::install("C:/Users/micha/Documents/geospaar/") to install locally

Data in packages

packages often include example data
Lazy loading data only loads when used
Lazy loaded data in data/ folder
- formats: .R, .rda, .RData, .tab, .txt, .csv
Non lazy loads (raw data) in inst/extdata

Rmarkdown demo by Lei Song

RMarkdown exercises

In your personal R project, Create new RMarkdown file using usethis::use_vignette(name = "example_vignette")
Create chunks for the following:
- Load the geospaar package
- Load the chirps data and print its structure using str(chirps)
- Plot chirps data using raster::plot(chirps). Above this chunk, include a text description for the CHIRPS data using different text formatting (bold, italics, etc). You can see information on the CHIRPS data in the man folder.
- Include a chunk with an obvious error, like 5 + "string"
- Try knitting this RMD using different chunk options
