Package: measure 0.0.1.9002

measure: A Recipes-Style Interface to Tidymodels for Analytical Measurements

Provides preprocessing steps for analytical measurement data such as spectroscopy and chromatography within the 'tidymodels' framework. Extends 'recipes' with steps for common spectral preprocessing techniques.
