R: Extract original data from 'flexsurvreg' objects.

model.frame.flexsurvreg {flexsurv} | R Documentation

## Extract original data from `flexsurvreg` objects.

### Description

Extract the data from a model fitted with `flexsurvreg`.

### Usage

    ## S3 method for class 'flexsurvreg'
    model.frame(formula, ...)

    ## S3 method for class 'flexsurvreg'
    model.matrix(object, par = NULL, ...)

### Arguments

`formula` | A fitted model object, as returned by `flexsurvreg`.
`...` | Further arguments (not used).
`object` | A fitted model object, as returned by `flexsurvreg`.
`par` | String naming the parameter whose linear model matrix is desired. The default value of `par=NULL` returns a matrix consisting of the model matrices for all models in the object `cbind`ed together, with the intercepts excluded. This is not really a “model matrix” in the usual sense, however, the columns directly correspond to the covariate coefficients in the matrix of estimates from the fitted model.

### Value

`model.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).
