{tinytable} 0.14.0 for #RStats makes it super easy to draw tables in html, tex, docx, typ, md & png.

There are only a few functions to learn, but don't be fooled! Small 📦s can still be powerful.

Check out the new gallery page for fun case studies.

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.

It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.

Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

Inspired by @nrennie.bsky.social excellent #TidyTuesday plot on the power of passports, I adapted the idea to look at refugee origins.

This chart ranks countries of origin of refugees, asylum-seekers, and others in need of international protection, grouped by region.

#RStats #ggplot2 #Refugees
Bump chart faceted by world regions showing the top countries of origin of refugees, asylum-seekers, and others in need of international protection. Asia and Africa rank consistently high, driven by long-term crises such as Afghanistan and Sudan. The Americas and Europe also appear high due to more recent crises in Venezuela and Ukraine.

Learned today about @OpenFreeMapOrg - free, high-quality vector tiles for your maps and apps!

Use them in #rstats with mapgl by passing the URL to the style param, e.g.:

maplibre(style = "tiles.openfreemap.or...")

Styles include "positron", "bright", and "liberty" with 3D!

Thing I just learned in #rstats: unz() lets you connect to a .zip and load files from inside it without actually unzipping it (great for a file I'm working with that's 30 MB zipped and 1+ GB unzipped, with multiple CSVs in it)
# unz() lets you connect to a .zip and treat it like a mini file system, # and you can load files from inside it one_zipped_csv_among_others <- readr::read_csv( unz("lotsa_zipped_csvs.zip"), "one_csv.csv" ) # readr::read_csv() can read a .zip with a single CSV in it one_zipped_csv <- readr::read_csv("big_zipped_file.zip")

One more bonus update with two changes:

1. A diverging color palette centered at 4% lets us see which counties are doing great or doing poorly
2. That size legend was spaced funnily, but we can make it more compact with {legendry}

Datawrapper version of a bar chart titled “U.K. election results 2024” shows party vote shares. Labour leads with 35.3% across the U.K., followed by the Conservatives at 23.7%. Reform UK has 14.3%, Liberal Democrats 12.2%, Greens 6.7%, and Others 6.8%. The Scottish National Party (SNP) reaches 30% in Scotland, translating to 2.5% of the total U.K. vote. ggplot2 version of a bar chart titled “U.K. election results 2024” shows party vote shares.
