We are looking for #rstats community feedback on 3 new dplyr functions!

We're aiming to expand the `filter()` family:

- `filter()` to keep rows
- `filter_out()` to drop rows
- `when_any()` and `when_all()` as modifiers

Read more and leave feedback here:
github.com/tidyverse/ti...
Example of using `filter_out()` on the `penguins` dataset, showing how it is much easier than `filter()`, especially with `NA`s

#TidyTuesday week 42

Had some fun experimenting with the {gt} package for this week data from the UK Met Office on historical weather and climate.

Code: github.com/rajodm/TidyT...

#dataviz #rstats #ggplot2
A table summarizing five UK climate zones identified from historical Met Office data (1981–2010). Clusters were derived using k-means analysis based on temperature, rainfall, sunshine, and number of air frost days variables. Each row represents a cluster: the first column shows station locations, the second lists the number of stations, and the remaining six columns present key weather characteristics.

Hello #dataBS (& especially #TidyTuesday) fam! I'm trying to organize a thing to help me keep TidyTuesday running smoothly, but first I need to get a bit of a runway. Every week I curate a TT dataset, and it's wearing me down. Please see github.com/rfordatascie... for some ways you can help! #RStats

My #TidyTuesday Week 32: Extreme Weather Attribution studies. thanks for curating @rajodm.bsky.social !!
A treemap chart titled 'Extreme Weather Attribution Studies' showing the breakdown of 620 studies by their conclusions about human climate influence. The chart is divided into two main sections: 'More severe or more likely N = 554' (left side, larger) and 'Less severe or less likely N = 66' (right side, smaller). In the larger left section, the biggest segments are Heat (196 studies, shown in orange), Rain & flooding (110 studies, in blue), Drought (74 studies, in yellow), Storm (46 studies, in gray), Compound events (32 studies, in light pink), Impact (30 studies, in coral), Wildfire (27 studies, in red), and Oceans (23 studies, in dark blue). In the smaller right section, the segments are Cold, snow & ice (37 studies, in light blue), Rain & flooding (20 studies, in blue), Storm (3 studies, in gray), Impact (2 studies, in coral), River flow (2 studies, in blue), and Drought (1 study, in yellow). The chart includes explanatory text stating that most extreme weather attribution studies conclude human influence has made extreme events more severe or likely, with Heat, Rain & flooding, and Drought being the most frequently reported. Data source is listed as Carbon Brief, dated TidyTuesday Week 32 2025

🌪️Extreme weather events attribution studies
Code: github.com/rajodm/TidyT...

#dataviz #rstats #ggplot2
Sankey diagram showing the flow of extreme weather attribution studies from geographic regions through event types to climate change impact classifications. The largest flows show Europe and East & Southeast Asia predominantly studying heat events and rain/flooding. Most studies found that climate change made events more severe or more likely to occur. Smaller portions found no discernible human influence, insufficient data, or that events became less severe or likely (mainly for cold, snow, ice, rain and flooding).

It is Tuesday already in New Zealand (yes I live in the future) so I am already sneeking a peek at the #TidyTuesday data. @rajodm.bsky.social has curated the dataset this week and it is about extreme weather attribution studies.

📊 Exploring #measles incidence and laboratory confirmation rates in Africa (2024).
Code: github.com/rajodm/TidyT...

#dataviz #rstats #ggplot2
Bivariate choropleth map of Africa showing measles incidence rates and laboratory confirmation rates by country in 2024. Countries are colored using a blue-to-purple matrix where blue indicates low incidence with high lab confirmation (like Botswana), red indicates high incidence with low lab confirmation (like Liberia), and purple indicates high incidence with high lab confirmation (like Somalia). The map shows significant variation in both disease burden and diagnostic capacity across African countries, with 89,765 total measles cases reported.

We're happy to see so many charts shared on Bluesky. ♥️

So, we prepared a chart, too. It shows the number of contributions for each prompt on Bluesky this year.

#30DayChartChallenge
A column chart which shows the number of posts shared for each prompt of the 30DayChartChallenge. The columns are coloured by the category the prompt belongs to. The category with the most contributions is Comparisons (days 1 to 6) with day 1 (Fractions) having the most contributions with 76. The number of posts decreased for the following categories. Day 11 is a peak with the prompt “Birds” (40 posts). Note: The prompt is determined by the tagged day in the post text in English, Spanish, French and German. If there is no match in the text, the number of the day in the month is used (UTC).
