  2. Basic Capabilities Survival Data Diagnostics Additional Summaries Basic Capabilities The RcmdrPlugin.survival package provides a graphical user interface (GUI) for some of the most widely facilities of the survival package: Estimating survival functions ( survfit ). Testing di¤erences in survival functions ( survdiff ). Fitting Cox-regression models ( coxph ). Fitting parametric survival-regression models ( survreg ).

  3. Basic Capabilities Survival Data Diagnostics Additional Summaries Survival Data The RcmdrPlugin.survival package provides the ability to de…ne and manipulate survival data: Survival-data de…nition (time and event variables, strata, clusters) saved as data-set attributes. Conversion from wide to long format for time-dependent covariates. Conversion of variables to date or Date objects.

  4. Basic Capabilities Survival Data Diagnostics Additional Summaries Diagnostics Model diagnostics from the survival package: Test and graphs for proportional-hazard assumption of Cox model ( cox.zph ) . Graphs of dfbeta and dfbetas for both Cox and parametric survival-regression models ( residuals methods for these models). Plots of null martingale residuals for Cox models ( residuals method). Partial-residual plots for Cox models ( residuals and fitted methods). Ability to add …tted values and residuals to the data set.

  5. Basic Capabilities Survival Data Diagnostics Additional Summaries Additional Summaries Other displays Plots of …tted survival functions based on Cox model. Quantiles of survival functions ( quantile method for survfit objects, from RcmdrPlugin.survival package). Tests Analysis of deviance tables for Cox and parametric survival-regression models ( anova , Anova from car package). Wald tests of linear hypotheses ( linearHypothesis from car package).
