R: Add Survival Curves of Pooled Patients onto the Main Plot

ggsurvplot_add_all {survminer} | R Documentation

## Add Survival Curves of Pooled Patients onto the Main Plot

### Description

Add survival curves of pooled patients onto the main plot stratified by grouping variables.

### Usage

    ggsurvplot_add_all(fit, data, legend.title = "Strata", legend.labs = NULL,
      pval = FALSE, ...)

### Arguments

`fit` | an object of class survfit.
`data` | a dataset used to fit survival curves. If not supplied then data will be extracted from 'fit' object.
`legend.title` | legend title.
`legend.labs` | character vector specifying legend labels. Used to replace the names of the strata from the fit. Should be given in the same order as those strata.
`pval` | logical value, a numeric or a string. If logical and TRUE, the p-value is added on the plot. If numeric, than the computet p-value is substituted with the one passed with this parameter. If character, then the customized string appears on the plot. See examples - Example 3.
`...` | other arguments passed to the `ggsurvplot()` function.

### Value

Return a ggsurvplot.

`ggsurvplot`

### Examples

    library(survival)

    # Fit survival curves
    fit <- surv_fit(Surv(time, status) ~ sex, data = lung)

    # Visualize survival curves
    ggsurvplot(fit, data = lung,
              risk.table = TRUE, pval = TRUE,
              surv.median.line = "hv", palette = "jco")

    # Add survival curves of pooled patients (Null model)
    # Use add.all = TRUE option
    ggsurvplot(fit, data = lung,
              risk.table = TRUE, pval = TRUE,
              surv.median.line = "hv", palette = "jco",
              add.all = TRUE)
