Control Functions

Control functions capture options in lists, and take care of defaults (and if it makes sense also checks). They avoid cluttering of function signatures with long lists of single arguments.

control_coxph(): Control Function for CoxPH Model

control_coxreg(): Controls for Cox regression

control_incidence_rate(): Control function for incidence rate

control_lineplot_vars(): Control Function for g_lineplot Function

control_logistic(): Control Function for Logistic Regression Model Fitting

control_step(): Control Function for Subgroup Treatment Effect Pattern (STEP) Calculations

control_summarize_vars(): Control Function for Descriptive Statistics

control_surv_time(): Control Function for survfit Model for Survival Time

control_surv_timepoint(): Control Function for survfit Model for Patient's Survival Rate at time point

Statistics Functions

Statistics functions should do the computation of the numbers that are tabulated later. In order to separate computation from formatting, they should not take care of rcell type formatting themselves.
