## S3 method for class 'flexsurvreg':
model.matrix(object, par=NULL, \dots)flexsurvreg.flexsurvreg.par=NULL returns a matrix consisting of
the model matrices for all models in the object cbinded
together, with the intermodel.frame returns a data frame with all the original
variables used for the model fit.
model.matrix returns a design matrix for a part of the
model that includes covariates. The required part is indicated by the
"par" argument (see above).flexsurvreg, model.frame, model.matrix.
