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.

It's Monday which mean my chaotic self is submitting last weeks #TidyTuesday. I chose to look at water access as most people had looked at food in much nicer ways than me.

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.

Anyone got any useful guides on Network Meta-Analysis in R?

Context I have done 1 in my life and despised it and swore I would never do one again. Alas that was not to be.

If I could avoid WINBUGS entirely that would be great

One of things that's stopped me using Quarto full time as opposed to officeR and an R script is the need to use loops to repeat image and table production.

I've now worked out how to run a loop within an R code chunk and images, tables as the loop runs so I get a nice doc

Back to ggplot2 because I was in a rush. British Library Funding

Significant downturn in funding post 2010. As prospective employers may see this one day, I don't speculate on the reason.

So I've split out the "Data Science/R Programmer/Python" part of my "main" profile because I found the fact people may be following me for Data content and just seeing relentless posts about Welsh rugby.
