Data management 101

Data audit

What are the different sources of data in your project? (This means, in how many places are data collected that are relevant to your project?)
What are the different types of data in your project? (e.g. Climate data, genome sequences, abundance data, traits, etc.)
At this moment, where are all the data stored? What is their organizational structure?
At this moment, in what ways are the data backed up?
At this moment, how much “meta-data” exists to explain your data to a collaborator or an external evaluator?

Principles of data organization

Data should be easily understood by you, collaborators, evaluators (e.g. reviewers), and computers
Sometimes, organizational strategies that work well for humans don’t work well for computers
Develop good practices that make data legible to both humans and computers
Keep your raw data raw! Make copies for cleaning.

Spreadsheet management

Almost everyone will manage data in a spreadsheet format
Remember that the spreadsheet is not a lab notebook
- Data on spreadsheets should have a “rectangular” format: rows and columns only
- Avoid encoding information by color or in margin text
Columns for variables; rows for observations
Leave no cell blank – develop a explicit mechanism for NA/blank/unmeasured values

Exercise

In today’s workshop we will be using the Portal Project Teaching Dataset
This comes from a longrunning study in Arizona regarding rodent and ant impacts on plant communities
- 40 year study, used in >100 publications to date!

Exercise

Let’s take a look at a “messy” version of a dataset that might be collected for a project like this.

Our dataset has two tabs. Two field assistants conducted the surveys, one in 2013 and one in 2014, and they both kept track of the data in their own way in tabs 2013 and 2014 of the dataset, respectively. Now you’re the person in charge of this project and you want to be able to start analyzing the data.

Your challenge: With a partner, look through this Google sheet and identify what problems you will have to address to create a “flat” sheet ready for analysis.

Make a copy of the sheet and start addressing issues
Work on this for ~10-15 minutes

Check-in

What are some improper practices you noticed?
How did you fix them?

Data management summary

Good research starts with good data management
Keep data rectangular
Try to work with “flat” data files as much as possible (csv, tsvs, etc.)
Keep raw data raw
Data should be readable by humans and by computers. (If there is conflict, keep the data readable by computers and include a README for humans)

Project organization and management

Start thinking in “nested hierarchies”

Why think about file structure?

Every file is stored somewhere on your computer
If you want to analyze it in R (or other programs), you will need to read it into memory

Code

read.csv("path/to/file.csv")

Unless managed properly, files are likely to be in different places on different computers.
- Major problems for collaboration, reproducing analyses, etc.

How file paths work

Each file path has the same structure:

parent-directory/sub-directory/sub-sub-directory/file.csv

We can describe file paths using absolute or relative notation.

Absolute paths

Absolute notation: the “starting point” is the “root” directory in your computer

Exercise:

Open RStudio and tab over to the “Terminal” pane on the bottom
- If you are working in an RProject, close the project.
Enter the command cd
Enter the command pwd
This is the starting point for all absolute paths you use on your computer.
- Notice: Everyone in this room will have a different path!
- Using absolute paths makes it harder to share code

Relative paths

Relative notation: Provide the path to a file relative to a “standard” starting point.

Exercise

Create a new Rstudio project, and call it “bioinformatics-workshop”
Save it on your Desktop for easy access
As you create it, select the “create with a git repository” checkbox - we will return to this.
In the terminal enter the command pwd
Notice that the first few directory names will be different, but after Desktop/, everyone should be in the bioinformatics-workshop subdirectory.

Organizing files within projects

What are some problems with this organization?

Some heuristics for good management

Hard and fast rules don’t always work - think about the needs of each project and decide accordingly
All work related to a given project should be housed within one directory (organize with sub-directories)
Many projects will need a few standard subdirectories: data, code, writing, admin, etc.
Raw data should be read-only (never change raw data)
Clean data should be generated through code (don’t hand-change files)
Carefully consider your naming scheme, and make it machine readable.
- Bad example: FINAL-figure2.png, FINAL-figure2-NEW.png
- Better example figures/figure2-20250324.png, figure/figure2-20250326.png

Exercise

Think about the different file types you have generated for your project so far.
Where are these files stored?
What would you have to do to “archive” these files for paper submission, or to share with your advisor?
When you sit down to analyze your data, where/how do you start?

Writing with Quarto/Markdown

Markdown overview

Markdown is a simple language that allows us to write in “plain” text and generate “rich” documents in Word, PDF, or HTML format.
- e.g. Adding *one asterisk* around text generates bold text: one asterisk
- Adding **two asterisks** around text generates bold text: two asterisks

Markdown exercise

In your bioinformatics-workshop RProject, create a new Markdown file.
Create a document that uses five of the Markdown features documented at this link: https://quarto.org/docs/authoring/markdown-basics.html

Integrating Markdown with code through quarto

Anatomy of a `qmd` file

(link to download this file)

Lines 1–5: “YAML” header - this is the space to add information about your file (title, author, date, additional details).

Demarcated by three dashes (---)
Always appear in key: value format
Lots of possible options – see this guide for details.
- No need to get overwhelmed by the options for now - but good to keep in mind for future projects.

Lines 7–15: R code chunk

Demarcated by three ticks, followed by the programming language name (```{r} {code} ```)
Lines 8–9 are options for the R code chunk - these control, e.g. whether the code is run or not, how big figures are, etc.
Lines 11–15 are standard R code

Lines 16–20: Text in Markdown

This is text meant to be read by humans
Can customize how text is rendered, e.g. adding * around a word to italicize: *quarto* becomes quarto
Read about additional formatting options here

What to do with `qmd` files

Render (i.e. “generate”) into a “public facing” document, with all the source code readily available.
Settings for rendering are based on the YAML header of the file

Exercise

In the same PRoject, create a new Quarto Document
Render the document to HTML and Docx
Tweak some of the code and verify that the new results are generated.

Publication-ready graphics with ggplot

We tend to make inferences about relationships between the objects that we see in ways that bear on our interpretation of graphical data, for example. Arrangements of points and lines on a page can encourage us—sometimes quite unconsciously—to make inferences about similarities, clustering, distinctions, and causal relationships that might or might not be there in the numbers. Sometimes these perceptual tendencies can be honestly harnessed to make our graphics more effective. At other times, they will tend to lead us astray, and must take care not to lean on them too much.

Illustrations like this demonstrate why it is worth looking at data. But that does not mean that looking at data is all one needs to do. Real datasets are messy, and while displaying them graphically is very useful, doing so presents problems of its own. As we will see below, there is considerable debate about what sort of visual work is most effective, when it can be superfluous, and how it can at times be misleading to researchers and audiences alike.

Principles for data visualization

All data visualizations map data values into quantifiable features of the resulting graphic.

— Clause Wilke, Fundamentals of Data Visualization

Mapping features of the data onto aesthetics of a graphic

Code

```{mermaid}
%%| collapse: true
%%| code-fold: true

flowchart LR
  A(Quantitative variable) --> B(Position on figure) --> F(Position on X-axis, Y-axis, ...)
  A --> C(Size of visual element)
  A --> D(Color of visual element)
```

flowchart LR
  A(Quantitative variable) --> B(Position on figure) --> F(Position on X-axis, Y-axis, ...)
  A --> C(Size of visual element)
  A --> D(Color of visual element)

Code

```{mermaid}
%%| collapse: true
%%| code-fold: true

flowchart LR
  A(Categorical variable) --> B(Shape of visual element) --> C(Shape of point, stroke of line)
  A --> D(Colour of visual element)
```

flowchart LR
  A(Categorical variable) --> B(Shape of visual element) --> C(Shape of point, stroke of line)
  A --> D(Colour of visual element)

Categorical variables can be ordered or unordered. Examples?

Mapping features of the data onto aesthetics of a graphic

How to choose the right map?
- The map should be capable of encoding the data
- e.g. Shapes are a poor choice for encoding quantitative variables
- The map should be effective at encoding the data
- The subject of research on how brains work

Identifying the geometry for the plot

The geometry determines how the data are shown
In ggplot, you can choose from a large number of geom_* functions, depending on whether you wish to show points, lines, boxplots, histograms, etc.

Setting the scale for the aesthetics

Code

```{mermaid}
%%| collapse: true
%%| code-fold: true

flowchart LR
  A(Quantitative variable) --> B(Position on figure) 
  A --> C(Size of visual element) 
  A --> D(Color of visual element) --> G(Species 1 should be blue, Species 2 should be green)
```

flowchart LR
  A(Quantitative variable) --> B(Position on figure) 
  A --> C(Size of visual element) 
  A --> D(Color of visual element) --> G(Species 1 should be blue, Species 2 should be green)

How to choose the right scale?

The scale should be capable of encoding the data you are presenting
e.g. If you have data on a dozen species, color might be a poor choice because human brains are not good at distinguishing between a dozen colors.
The scale should be efficient at encoding the data you are presenting
E.g. Diverging data (e.g. “least likely to most likely”) best represented by a divergent palette

For simplicity, we’ll work with data for the 6 largest countries (by population) as of 2007.

Code

biggest <- gapminder |> 
  filter(year == 2007) |> 
  arrange(-pop) |> 
  head()
gapminder_big <- 
  gapminder |> 
  filter(country %in% biggest$country)

Same data, different aesthetics

Map country to color; Year to X-axis, Life Expectancy to Y-axis.

Code

gapminder_big |> 
  ggplot(aes(color = country, x = year, y = lifeExp)) + 
  geom_point()

Map year to color; per-capita GDP to X-axis, Life Expectancy to Y-axis.

Code

gapminder_big |> 
  ggplot(aes(color = year, x = gdpPercap, y = lifeExp, group = country)) + 
  geom_point()

Same aesthetics, different geometries

Map country to color; Year to X-axis, Life Expectancy to Y-axis. Show points for each entry.

Code

gapminder_big |> 
  ggplot(aes(color = country, x = year, y = lifeExp)) + 
  geom_point()

Map country to color; Year to X-axis, Life Expectancy to Y-axis. Show lines for each entry.

Code

gapminder_big |> 
  ggplot(aes(color = country, x = year, y = lifeExp)) + 
  geom_line()

Map country to color; Year to X-axis, Life Expectancy to Y-axis. Show points and lines for each entry.

Code

gapminder_big |> 
  ggplot(aes(color = country, x = year, y = lifeExp)) + 
  geom_line() + 
  geom_point()

Note that sometimes, graphs have the right syntax but are meaningless

Code

gapminder_big |> 
  ggplot(aes(color = country, x = year, y = lifeExp)) + 
  geom_boxplot()

See also Noam Chomsky’s “Colorless green ideas sleep furiously”

Same aesthetics and geometries, different scales

Map country to color; Year to X-axis, Life Expectancy to Y-axis. Show points and lines for each entry. Use default scales.

Code

gapminder_big |> 
  ggplot(aes(color = country, x = year, y = lifeExp)) + 
  geom_line() + 
  geom_point()

Map country to color; Year to X-axis, Life Expectancy to Y-axis. Show points and lines for each entry. Scale the colors manually.

Code

gapminder_big |> 
  ggplot(aes(color = country, x = year, y = lifeExp)) + 
  geom_line() + 
  geom_point() + 
  scale_color_manual(values = c("red", "orange", "yellow", 
                                "blue", "green", "purple"))

Map country to color; Year to X-axis, Life Expectancy to Y-axis. Show points and lines for each entry. Scale the colors using a pre-defined palette.

Code

gapminder_big |> 
  ggplot(aes(color = country, x = year, y = lifeExp)) + 
  geom_line() + 
  geom_point() + 
  scale_color_brewer(palette = "Set1")

Think for yourself:

What kind of information is encoded in this sheet?
What are some relationships I can explore?
How can I map properties of the data onto aesthetics of the graph?
How can I choose meaningful scales for the mapping?

Modify the following code to create your graph:

# library(tidyverse)
# library(palmerpenguins)
penguins |> 
  ggplot(aes(y = bill_length_mm, x = flipper_length_mm)) +
  geom_point(aes(shape = species), color = 'limegreen') +
  theme_bw()

Here are some resources to help explore potential aesthetics and mappings:
