Plots can be stratified by any variable in the dataframe like Death and dc :
We will here use the swimmer_plot function and the dataset created in the Data & Function page and the stratify = option.
# Libraries
library(ggplot2)
library(swimplot)#Stratifaction

col="black",alpha=0.75,width=.8,base_size = 14,stratify= c('Death','dc')) +
xlab("ID")+
