A weekly data project aimed at the R ecosystem. As this project was borne out of the R4DS Online Learning Community and the R for Data Science textbook, an emphasis was placed on understanding how to summarize and arrange data to make meaningful charts with ggplot2, tidyr, dplyr, and other tools in the tidyverse ecosystem. However, any code-based methodology is welcome - just please remember to share the code used to generate the results.
Join the R4DS Online Learning Community in the weekly #TidyTuesday event! Every week we post a raw dataset, a chart or article related to that dataset, and ask you to explore the data. While the dataset will be “tamed”, it will not always be tidy! As such you might need to apply various R for Data Science techniques to wrangle the data into a true tidy format. The goal of TidyTuesday is to apply your R skills, get feedback, explore other’s work, and connect with the greater #RStats community! As such we encourage everyone of all skills to participate!
We will have many sources of data and want to emphasize that no causation is implied. There are various moderating variables that affect all data, many of which might not have been captured in these datasets. As such, our guidelines are to use the data provided to practice your data tidying and plotting techniques. Participants are invited to consider for themselves what nuancing factors might underlie these relationships.
The intent of Tidy Tuesday is to provide a safe and supportive forum for individuals to practice their wrangling and data visualization skills independent of drawing conclusions. While we understand that the two are related, the focus of this practice is purely on building skills with real-world data.
All data will be posted on the data sets page on Monday. It will include the link to the original article (for context) and to the data set.
We welcome all newcomers, enthusiasts, and experts to participate, but be mindful of a few things:
- The data set comes from the source article or the source that the article credits. Be mindful that the data is what it is and Tidy Tuesday is designed to help you practice data visualization and basic data wrangling in R.
- Again, the data is what it is! You are welcome to explore beyond the provided dataset, but the data is provided as a "toy" dataset to practice techniques on.
- This is NOT about criticizing the original article or graph. Real people made the graphs, collected or acquired the data! Focus on the provided dataset, learning, and improving your techniques in R.
- This is NOT about criticizing or tearing down your fellow
#RStatspractitioners or their code! Be supportive and kind to each other! Like other's posts and help promote the#RStatscommunity! - Use the hashtags #TidyTuesday and #RStats on Twitter if you create your own version and would like to share it.
- Include a picture of the visualisation when you post to Twitter.
- Include a copy of the code used to create your visualization when you post to Twitter. Comment your code wherever possible to help yourself and others understand your process!
- Focus on improving your craft, even if you end up with something simple!
- Give credit to the original data source whenever possible.
TidyTuesday is built around open datasets that are found in the "wild" or submitted as Issues on our GitHub.
If you find a dataset that you think would be interesting, you can approach it through two ways:
-
Submit the dataset as an Issue
a. Find an interesting dataset
b. Find a report, blog post, article etc relevant to the data
c. Submit the dataset as an Issue along with a link to the article -
Create an entire TidyTuesday challenge!
a. Find an interesting dataset
b. Find a report, blog post, article etc relevant to the data (or create one yourself!)
c. Let us know you've found something interesting and are working on it by filing an Issue on our GitHub
d. Provide a link or the raw data and a cleaning script for the data
e. Write a basicreadme.mdfile using the minimal template below and make sure to give yourself credit!
# INPUT THE SUBJECT TITLE OF THE DATASET
The data this week comes from [SOURCE_OF_DATA](URL_TO_DATA).

Please add alt text (alternative text) to all of your posted graphics for #TidyTuesday.
Twitter provides guidelines for how to add alt text to your images.
The DataViz Society/Nightingale has an article on writing good alt text for plots/graphs.
Here’s a simple formula for writing alt text for data visualization:
It’s helpful for people with partial sight to know what chart type it is and gives context for understanding the rest of the visual. Example: Line graph
What data is included in the chart? The x and y axis labels may help you figure this out. Example: number of bananas sold per day in the last year
Think about why you’re including this visual. What does it show that’s meaningful. There should be a point to every visual and you should tell people what to look for. Example: the winter months have more banana sales
Don’t include this in your alt text, but it should be included somewhere in the surrounding text. People should be able to click on a link to view the source data or dig further into the visual. This provides transparency about your source and lets people explore the data. Example: Data from the USDA
Penn State has an article on writing alt text descriptions for charts and tables.
Charts, graphs and maps use visuals to convey complex images to users. But since they are images, these media provide serious accessibility issues to colorblind users and users of screen readers. See the examples on this page for details on how to make charts more accessible.
The {rtweet} package includes the ability to post tweets with alt text programmatically.
Need a reminder? There are extensions that force you to remember to add Alt Text to Tweets with media.
