ggflexsurvplot
mult_var = flexsurvreg(Surv(START,STOP,event) ~ cont1+cat1+cat2, data=es_all, dist="weibull") p=ggflexsurvplot(mult_var, xlab = "Time (Days)", censor = F, title = "Multivariate - Weibull fit")
In ggflexsurvplot, unable to separate strata lines of KM, weibull fit from multivariate model to different plots. is it possible to separate in plot level? or use fit data and then can do using ggplot? If yes with fit data, how can we extract fit data from ggflexsurvplot?
