Track trends and transitions with ggbump, an R package that extends ggplot2 by providing tools to create elegant bump charts. Ideal for visualizing changes in rankings over time, ggbump helps you craft clear and impactful visualizations. Why use ggbump? ✔️ Specialized for ranking comparisons: Create bump charts to effectively display how rankings or relative positions shift across categories or time periods. ✔️ Highlight patterns and trends: Showcase transitions with smooth, visually appealing lines, making trends easier to interpret. ✔️ Smooth and customizable aesthetics: Use ggplot2’s flexibility to adjust line styles, colors, and themes, ensuring your charts align with your data story. When to use bump charts and alternatives: Bump charts are best for highlighting changes in rankings or relative positions over time across multiple groups. If your focus is on absolute values or continuous trends, consider alternatives like line charts or stacked area charts. The example visualizations shown here originate from the ggbump GitHub repository, demonstrating the package’s ability to create engaging and insightful bump charts: github.com/davidsjoberg/g… Explore more advanced visualizations in R and learn about ggplot2 extensions in my online course, "Data Visualization in R Using ggplot2 & Friends!"

Creating publication-ready plots in R is easier than ever with ggpubr. This extension for ggplot2 simplifies the process of generating clean and professional graphics, especially for exploratory data analysis and reporting. The attached visual, which I created using ggpubr, demonstrates its versatility. It includes a density plot with group comparisons (upper right), a boxplot with statistical significance annotations (lower left), and a grouped bar chart (lower right). These examples showcase how ggpubr helps streamline the creation of informative and visually appealing plots, perfect for presentations and publications. If you’d like to learn how to create publication-ready visualizations with ggpubr and other tools, join my online course, Data Visualization in R Using ggplot2 & Friends. In this course, you’ll learn how to design polished graphics like these step-by-step!

The tidyplots package is an excellent tool for creating data visualizations in R. But the package itself is not the only highlight. It also comes with exceptionally well-written documentation. Jan Broder Engler, the developer of tidyplots, has not only created the package but also written a full paper that explains how to use it in practice. The tidyplots paper is a great example of how package documentation can be done well. It clearly introduces the main ideas behind the package and shows how complex visualizations can be created with concise and readable code. Throughout the paper, the tidyplots workflow is explained step by step. It shows how the package builds on ggplot2 while adding convenient helper functions and a tidyverse-style syntax. This approach makes it easier to create clean and consistent plots without writing long and complicated ggplot2 code. Another strong aspect of the paper is the combination of explanations and practical examples. This makes it easy to follow along and understand how different types of visualizations are created while keeping the syntax consistent across tasks. If you want to improve your data visualization workflow in R, the tidyplots paper is definitely worth reading. You can find it here: onlinelibrary.wiley.com/doi/10.1002/im… I also recently published a Statistics Globe Hub module where I introduce tidyplots and show how to apply it using practical examples and exercises. If you are not yet part of the Statistics Globe Hub, it is an ongoing learning program where I release a new module every week covering topics in statistics, data science, AI, R, and Python. Join the Hub now to get immediate access to the tidyplots module and all other modules released this month.

Augmented feedback (knowledge of results) via velocity monitoring increases training quality (velocity output) during strength and power orientated training. Rep by rep feedback drives intent of effort

ASR v0.0.1 is now available inside Agile Periodization Skool for $35/month: skool.com/agileperiodiza… This is a fully functioning version, not a teaser. More instructional videos and walkthroughs are coming, but I wanted members to get early access now so they can start using it and help shape where it goes next. The main idea behind ASR is simple: back to paper. I want fewer athletes staring at phones and screens during training. Paper is still one of the best coaching interfaces we have. The challenge is making paper-based prescriptions modular, flexible, and easy to adjust in real time. That is what ASR solves. ASR helps coaches build smarter printout systems using modular prescription logic that combines ballpark estimates with quality-control metrics like eRIR, giving athletes practical options while keeping the session structured and coach-led. Available now for Skool members. Individual purchase coming soon. #AgilePeriodization #StrengthAndConditioning #SportsScience #CoachingTools #ExcelForCoaches

This is a short trailer clip from my longer presentation where I lay out the big picture of conditioning for MMA—and why most “conditioning plans” fail for a simple reason: They don’t respect the microcycle. In MMA, the hard part isn’t finding methods. The hard part is placing them around skill work, sparring, and recovery so you build the engine without hijacking performance. In the full talk + PDF draft bundle, I cover: - How I think about conditioning inside the MMA week (microcycle first) - How to protect key skill/sparring sessions while still progressing fitness - Why “energy systems templates” break when they meet real MMA training - How to iterate the plan week-to-week using feedback (Agile-style) Get the full bundle (€9.99): payhip.com/b/h04T6 Join the Skool community (discussion + Q&A): skool.com/agileperiodiza… If you coach fighters (or you are one), take this as a reminder: conditioning is not just physiology — it’s planning. #agileperiodization #mma #conditioning #strengthandconditioning #coaching #sportsperformance #combatSports #periodization #microcycle

Magnitude based inference has been severely discredited. Bayesian statistics are more widely misused by non-experts than p-values. Learn best practices in hypothesis testing, instead of switching to techniques you understand even less: lakens.github.io/statistical_in…

Conditioning for MMA isn’t hard to do — it’s hard to place. Most plans fail because they ignore the microcycle: conditioning steals quality from skill/sparring and recovery collapses.

Too many vector shapes can slow down PDF performance. This is how you can selectively rasterize data points in #tidyplots 🪩 In this example, I used 100 DPI for demonstration purposes. In practice, you would typically use 300 DPI for better quality 😉 #rstats #dataviz #phd
