One has to ask, did they even bother with a power review?

Still the paper got traction on the BBC and other news websites and, in the end, that's all that matters

You remember that Nature Aging paper about how multilingualism protects against accelerated aging? Well…

Family/Christmas/Birthday/Work means this may be the last attempt at #TidyTuesday this year. First full year doing it and enjoyed. Not sure if I got better though!

Working with datasets that definitely require the use of data.table. Genuinely very impressive package #rstats

Here's a good one. Rendering my quarto html in #positron causes loads of errors implying that quarto isn't installed correctly (I've uninstalled and reinstalled multiple times) but if render the same html in #RStudio, it renders with no drama

Anyone here better with the ggsankey package than I am? - I am trying to label the flow with the number of people transitioning through each stage. I have found no examples on the internet of labeling the flow (plenty labeling the nodes).

I have below what I need to try

Looked at the percentage of Oxbridge educated people who have won various British Literary Prizes for #TidyTuesday. I used ggbrick and, as the bricks of look like books, tried to make it look like they were in bookshelves with meh results.

If anybody has any good tips/resources for a statistical programmer who has a technical interview as a data scientist, let me know. I've not done one before

(Background is epidemiology and clinical trials but this would be in health data science looking at massive datasets)

As a Welshman, taking the opportunity to ignore the English and focus only on Wales for #TidyTuesday. Looking at the average weather for Wales in 2024 and now I've made myself homesick.

I do like #positron but RStudio allows me to create .tex files from new.

Anyone know how I could get this on #positron, or is not a thing yet?

Tried the datapasta package out, which is a form of minor miracle to get the country codes for the players.

Managed to crack a map of grandmasters per country before flying home to the UK for a break

For #TidyTuesday / #PydyTuesday I have struggled with the port of patchwork over to python. If anyone has any ideas on how to fix the titles of the graphs, I'm all ears.

Also Plotnine is a minor miracle.

In a vain attempt to keep learning python I have tried imputing some CDISC data using #Quarto and so on - the report is rough around the edges but at least it worked.
