Makes sense. I imagine this would simply be my primary use case, and I would prefer not having to refer to `x` twice. Something like:

replace_values <- function(x, ..., from=NULL, to=NULL, lookup=NULL){
if(! is.null(lookup)){
from <- names(lookup)
to <- lookup
}
...
}

This looks great! I think it would be neat if the functions also supported named look-up vectors in addition to the `to` and `from` arguments :)

Haha, would also be a succinct summary of most of my academic work 😅

And lastly, a big shout-out to @wkhuber.bsky.social and @s-anders.bsky.social!

I also encourage everyone to checkout the parallel efforts by groups around the world who came to similar conclusions:

*We benchmarked scGPT, scFoundation, GEARS, CPA (which claim predictive ability), and scBERT, Geneformer, and UCE (which do not claim this ability). I can't comment on methods released in the last 5 months. For a summary of recent developments, see @ekernf01.bsky.social's post

That's amazing. Congratulations 🎉

With {tidylog}, you see friendly messages like:

summarise: now 3 rows and 3 columns, ungrouped

filter: removed 2 rows (67%), one row remaining

✨ It’s like having a gentle co-pilot, helping you track what each step is doing — super useful for debugging and learning!

A friend of mine recommends the Bahnstadt Edeka Fleischtheke. (Vegetarian myself, so no first-hand experience 😅)
