h_plot_data_df: Preparing Data for Plotting
In 0liver0815/onc-crmpack-test: Object-Oriented Implementation of CRM Designs

This helper function prepares a data.frame object based on Data class object. The resulting data frame is used by the plot function for Data class objects.

1	h_plot_data_df(data, blind = FALSE, ...)

`data`	(`Data`) object from which data is extracted and converted into a data frame.
`blind`	(`flag`) should data be blinded? If `TRUE`, then for each cohort, all DLTs are assigned to the first subjects in the cohort. In addition, the placebo (if any) is set to the active dose level for that cohort.
`...`	further arguments passed to `data.frame` constructor. It can be e.g. an extra `column_name = value` pair based on a slot from `x` (which in this case might be a subclass of `Data`) which does not appear in `Data`.
