Can someone explain to me why this error message keeps coming up? My previous time-to-event analyses have all worked perfectly with the same commands. Tank you.
My skript contains the following:
dfit <- survfit2(Surv(time, status) ~ intervention, data = Drugs_discon)
summary(dfit)
ggsurvfit(dfit)
Error in ggsurvfit():
! ggsurvfit() cannot be used to plot objects of class <survfit2/survfitms/survfit>.
ℹ Use ggcuminc() for competing risks cumulative incidence plotting.
Run rlang::last_trace() to see where the error occurred.
