Jsgro episode 2 draft by jsgro · Pull Request #23 · carpentries-incubator/better-research-software-r

jsgro · 2025-10-30T17:08:20Z

Edited at least the top half of Episode 2 to change from Python to R (.e.g. change .py to R; change VS Code to RStudio).
I have not yet changed the Instructor panels about VS Code.
Other changes:

added spacewalks.Rproj to the first series of git add.
added -F when using ls to clearly show what is a directory vs a file.
added information about specific Mac aspects:
- explain @ presence in ls -laF command
- mention .DS_Store
offered 2 options to run the code the first time: in RStudio, or using RSCRIPT

Suggestion for next edit: move the creation of .gitignore to this episode as we have at least one dot file due to R: .Rproj.user and Mac users will also have .DS_Store. Also, I noted that when updating the eva_data_analysis.R script .gitignore is created automatically. So we can wait for that to happen, or preempt and create it before running the script.

…ce/issue-14 Translate og code python -> R

Made a few change on removing VSCode Terminal.

Update ls output. Add -F. Add ls command to see ".git". Update git status to R file.

Edit section with first commits, and add/edit some explanatory text.

update ls -laF files to match after creating project. Edit more lines.

Update section with filename changes and code change.

🆗 Pre-flight checks passed 😃

This pull request has been checked and contains no modified workflow files or spoofing.

It should be safe to Approve and Run the workflows that need maintainer approval.

Revise ls output as sometimes. `.DStore` does not always show up to removed from `ls` and `git` commands. ADDED a section to add `.gitignore` with `echo` as was done in the Python version (avoids any editor issues.) I will open an ISSUE about running the code regarding `library(lubridate)`.

Added a code update moving the `library(lubridate)` one line up so that the code functions. Look at files created. Update git status.

Added a git status and its clean output

fixed challenge and solution close tags with colons ::: etc

(Copy of comment I mistakenly had added to my own branch)
IMPORTANT ADDITION on running the code: R is often run from the RStudio GUI, but to be closer to the Python version and also provide relevant information I provided both RStudio GUI as well as Shell Terminal using RSCRIPT command to run the code.

IMPORTANT ADDITION made to the episode:

Once we update the Paths to the files at the top of the R Script there is no suggestion to try if the code now runs (that aspect was also lacking in Python version).
However, unlike the Python code, changing the Paths to the files is not enough as the code still has one error (that I think was not intentional) in the sense that the library(lubridate) command has to be one line up and before the line date = Date() since Date() is a function of lubridate. This is also an opportunity to trouble shoot code once more with a different type of error.

IMPORTANT ADDITION: I also moved the .gitignore file creation to this episode as using RStudio will create a .Rproj.user hidden directory, possibly also .Rhistory and on Macs we might see also .DS_Store depending on the order of creation of files/directory etc. This allow to use .gitingnore at this point and get a "clean" slate when checking git status so that we don't have to carry all these Untracked files along to the next episode.

I made these decision along the way as they seemed the best way to approach the changes and differences with the Python version.
