Lots of Package News
I’ve sent a slew of packages to CRAN recently (thanks to Swetlana and Uwe). There are updates to:
caretwas primarily updated to deal with an issue introduced in the last version. It is a good idea to avoid fully loading the underlying modeling packages to avoid name conflicts. We made that change in the last version and it ended up being more complex than thought. A quirk in the regression tests missed it too but the whole thing can be avoided by loading the modeling package.newsfilersamplehad some modest additions including bridges tocaretandrecipes. The website added more application examples (times series and survival analysis).newsfilerecipeshad more substantial enhancments including six new steps, a better interface for creating interactions (using selectors), and the ability to save the processed data in a sparse format.newsfileCubistandC50have been updated and brought into the age ofroxygenandpkgdown.C5.0now has a nice plot method a lapartykitand now has a vignette. I’ll be adding a few features to each over time.
Two new packages:
yardstickcontains many of the performance measurement methods incaretbut in a format that is easier to use withdplyrsyntax and functional programming.tidyposterioris a Bayesian version ofcaret’sresamplesfunction. It can be used to take the resampling results from multiple models and do more formal statistical comparisons. It is similar in spirit to Benavoli et al (2017). We are looking for nominations for the hex logo so please offer your suggestions (but keep it clean).
