The tools in this package are intended to help researchers assess multiple treatment-covariate interactions with data from a parallel-group randomized controlled clinical trial.


NEWS file for R project ANOINT

Version 1.1

The package formerly named mim has been renamed ANOINT for analysis of interactions.

Version 1.1 has packaged the methods from the previous versions into a class anoint and The anoint class holds the information about the model fit formula, candidate treatment-response factor (interaction terms), and the results of the selection procedure, if requested. The class performs all of the ANOINT methods (one-by-one, unrestricted interaction model, and proportional interaction) and provides methods to inspect and summary their results.

Corrected error in additional intercept in select.glmnet. Added stepAIC selection and changed select argument to taking character specifying type of selection method.

Added na.action to anoint.


Version 1.3

Added pim.subsets function.

Revised forestplot labels and handling of factors.

Added forest.subsets for plotting best subsets.
