@Max mentioned a tidymodels extension of {recipes} for spectrometric, spectroscopic, or chromatographic data at the rstudio::conf keynote on tidymodels. Broadly, I refer to this as "characterization" data in that it is data characterizing a sample or product.
I'm hoping to kick start a discussion on how to build out this extension. I'm very open on thoughts about (a) is this useful, (b) what is a reasonable starting point, and (c) what data types are in scope?
