The Reproducible Scientist

If your science can’t be repeated, it’s not science — it’s a story that can’t be told again.

Every R user eventually faces the same haunting truth: our scripts sprawl, our data scatter, and our insights vanish in half-finished notebooks.
Reproducibility is not a luxury — it’s the oxygen of modern data work.

🗂 The Anatomy of a Reproducible Project

Order is not bureaucracy. It’s mercy for your future self. A clean project structure turns chaos into clarity:

my-project/
├── data/
│   ├── raw/
│   └── processed/
├── R/
│   ├── functions.R
│   └── analysis.R
├── outputs/
│   ├── figures/
│   └── reports/
├── README.md
└── my-project.Rproj

This is your lab bench — every tool, every specimen in its place.

📄 The Power of R Markdown and Quarto

Reproducibility isn’t just about code — it’s about narrative.

---
title: "Elephant Weight Study"
author: "Notivra Team"
output: html_document
---

```{r}
library(ggplot2)
ggplot(df, aes(weight_kg)) + geom_histogram()

In this single file, code and reasoning live together — no more “forgot which script produced this figure.”
R Markdown and Quarto turn analysis into an essay: human-readable, machine-executable.

🧮 Version Control as Memory

Git is not only for programmers. It’s for scientists with memory loss.

  • git init — start your timeline.
  • git commit -m "added data cleaning script" — freeze a moment.
  • git diff — watch how your thinking evolved.

Each commit is a fossil record of your intellect.

🔁 From Projects to Pipelines

As your work grows, reproducibility means automation. Tools like targets or drake let you define what depends on what, and rebuild only what changes.

library(targets)

tar_pipeline(
  tar_target(raw_data, read.csv("data/raw/field.csv")),
  tar_target(clean_data, clean(raw_data)),
  tar_target(summary, summarize(clean_data))
)

Now your analysis isn’t a one-off — it’s a machine of truth.

🧠 Reflection

What would happen if someone reran your project a year from now?
Would they get the same story?

📘 Try It Yourself

  1. Create a new RStudio Project.
  2. Organize it with data/, R/, and outputs/.
  3. Write your analysis in an R Markdown file.
  4. Save your first commit with Git.

You’ve just taken your first step from chaos to clarity.

Reproducibility is not about remembering what you did —
it’s about never needing to remember at all.
