A colleague has been sending benchmarks after he essentially added arrow::to_duckdb() to our {dplyr} pipelines and my mind is being blown. Exciting times!

A couple of blog posts on pharmacokinetic models that I hadn't gotten around to sharing before:

https://blog.djnavarro.net/non-compartmental-analysis/

https://blog.djnavarro.net/stan-ode/

The first one talks about non-compartmental analysis and has some very simple R code, the second one dives a little deeper and talks about compartmental models - which often require you to use an ODE solver in the model - in Stan and R.

I'm still learning pharmacokinetics so they're a little rough around the edges

I asked Bard how to read in a .mseed file into

If the seismology package existed and worked in this way I would be interested. But in terms of getting up and running with this specialist binary file, I would have been better (had I not known my options before hand) to use a more traditional source that restricted itself to indexing websites rather than making up convincingly communicated answers.

“It’s a bit like seeing a rabbit shape in the clouds and then testing whether all clouds look like rabbits… using the same cloud. I hope you appreciate that you’re going to need some new clouds to test your theory.

Any datapoint you use to inspire a theory or question can’t be used to test that same theory.”

I'm very excited to be presenting at R/Medicine this year! 🎉🎉🎉

I'll be talking about using {tsfeatures} and {tidymodels} to fit ML models to time series data in order to detect heart murmurs💡

Someone messaged me on linkedin asking if Rust 🦀 could speed up their R code? :rstat:
It's business critical but literally takes a day to run.

Using base R i got a 7x speed up.
Using Rust? I got a 200x speed up.

I cannot overstate how amazing Rust is for R.

Would you be intersted in a video on this process of speeding up R code and then rewriting in Rust?

folks, I'm trying to hack a bit of extra functionality into and I want to add a custom class to a plot and then overload the "+" operator for that class to do stuff. I'm doing this (code on next post), but I get

Error in g + geom_point() : non-numeric argument to binary operator  
In addition: Warning message:  
Incompatible methods ("+.modified", "+.gg") for "+"  

What am I doing wrong?

On a totally unrelated note, I still don't understand who is out there using reticulate frictionlessly. Every single time I try to set anything up I get errors upon errors.

In case you were wondering, chatGPT (chat.openai.com) gives incorrect answers to quiz questions(a quiz that is required to pass if an individual wishes to be an R tutor on Wyzant). How do I know? Because I'm a tutor on Wyzant, and I just tested openai.com. It failed. The question is... Should we all be concerned? And if so, what should we be concerned about?

Looking for psychologists on here, both researching and practicing, especially queer, disabled and BIPOC psychologists.

I’m starting out as a psychology student and would love to follow more people in the field.

Anyone around?
