= 100, # break X axis in time intervals by 500. xlab = "Time in days", # customize X axis label. Xlim = c( 0, 500), # present narrower X axis, but not affect # survival estimates. conf.int = TRUE, # show confidence intervals for # point estimates of survival curves. pval = TRUE, # show p-value of log-rank test. data = lung, # data used to fit survival curves. ggcompetingrisks(): Plots cumulative incidence curves for competing risks.įind out more at, and check out the documentation and usage examples of each of the functions in survminer package.įit, # survfit object with calculated statistics.Ggcoxadjustedcurves(): Plots adjusted survival curves for coxph model. Ggforest(): Draws forest plot for CoxPH model. It helps to properly choose the functional form of continuous variable in cox model.

Ggcoxfunctional(): Displays graphs of continuous explanatory variable against martingale residuals of null cox proportional hazards model. Ggcoxdiagnostics(): Displays diagnostics graphs presenting goodness of Cox Proportional Hazards Model fit. Displays a graph of the scaled Schoenfeld residuals, along with a smooth curve using ggplot2. Ggcoxzph(): Graphical test of proportional hazards. Calculate pairwise comparisons between group levels with corrections for multiple testing. Pairwise_survdiff(): Multiple comparisons of survival curves. Provides a value of a cutpoint that correspond to the most significant relation with survival. Surv_cutpoint(): Determines the optimal cutpoint for one or multiple continuous variables at once. Compared to the default summary() function, surv_summary() creates a data frame containing a nice summary from survfit results. Surv_summary(): Summary of a survival curve. Ggsurvevents(): Plots the distribution of event’s times. Ggsurvplot(): Draws survival curves with the ‘number at risk’ table, the cumulative number of events table and the cumulative number of censored subjects table.Īrrange_ggsurvplots(): Arranges multiple ggsurvplots on the same page. The main functions, in the package, are organized in different categories as follow. The survminer R package provides functions for facilitating survival analysis and visualization.
