msmtools {msmtools}

Building augmented data for multi-state models: the msmtools package

Description

msmtools introduces a fast and general method for restructuring classical longitudinal datasets into augmented ones. Augmented data enhances longitudinal datasets and allow to model each transition under a multi-state framework. msmtools works in symbiosis with the msm package. It also provides two graphical goodness-of-fit tools to inspect the model performances using survival curves and prevalences under the Markov assumption. msmtools comes with 4 functions: augment, polish, prevplot, and survplot.
