[R] Assessing calibration of Cox model with time-dependent coefficients

I am trying to find methods for testing and visualizing calibration to Cox models with time-depended coefficients. I have read this nice article . In this paper, we can fit three models: fit0 <- coxph(Surv(futime, status) ~ x1 + x2 + x3, da
