typical.ordered() for R-devel compatibility.data_grid() to work with dev tidyr.add_predictions(), gather_predictions(), and spread_predictions() more carefully pass along type parameter in order to avoid problems with predict methods that don’t deal with type = NULL (#92).add_predictions(), gather_predictions(), and spread_predictions() gain a type parameter which is passed through to stats::predict() (#34, @pmenzel)
New crossv_loo() which implements leave-one-out cross validation (@pmenzel)
typical() no longer ignores missing values in character and factor vectors (#80).
data_grid() no longer fails with modern tidyr (#58).
New mape() and rsae() model quality statistics (@paulponcet, #33).
rsquare() use more robust calculation 1 - SS_res / SS_tot rather than SS_reg / SS_tot (#37).
typical() gains ordered and integer methods (@jrnold, #44), and ... argument (@jrnold, #42).
Added a NEWS.md file to track changes to the package.
