Extract a data.frame containing the estimated survival curves from a adjustedsurv object

as_ggsurvplot_df.Rd

A small convenience function to extract the most important quantities from an adjustedsurv object. The resulting data.frame is structured according to the format required by the ggsurvplot_df function of the survminer package, making it easy to use the ggsurvplot_df function.

Usage

as_ggsurvplot_df(adjsurv)

Arguments

adjsurv

An object of class adjustedsurv created by the adjustedsurv function.

Value

Returns a data.frame containing the required information, extracted from the adjustedsurv object.
