My Quarto #rstats tip for big/complex papers is to set up R scripts that do data processing/modeling & save plots/outputs as RDS files. The Quarto can then load the RDS file & make any modifications to the ggplot2 object before plotting. This avoids unwieldy long Quarto docs /w complex caching.

If you see emojis in my R code, it definitely wasn’t ChatGPT, it was me, because I’m cool and young

In predictive modeling, we use spatial resampling to evaluate how the model performs in different regions of the space. Here is an example with spatialsample in the #tidymodels framework.

1. LLM-generated code tries to run code from online software packages. Which is normal but
2. The packages don’t exist. Which would normally cause an error but
3. Nefarious people have made malware under the package names that LLMs make up most often. So
4. Now the LLM code points to malware.
