Bootstrap coxph model in R

Question

[Palgrave]

I have a survival model calculated like this:

mv.cox <- coxph(Surv(as.numeric(Time), as.numeric(Status))  ~Sex, data = as.data.frame((df))) 

I am looking for a way to calculate a bootstrap for this model/data that should include the Hazard ration, CI and p-value.

I tried using the the following, but it does not give the Hazard or p-value:

library(coxed)

coxed(model, method="npsf", bootstrap = TRUE, B=1000)

I also tried the rms package:

require(rms)

mv.cph <- cph(Surv(as.numeric(Time), as.numeric(Status))  ~df$miRNA,x=T,y = T, data = as.data.frame((df))) 
bootcov(mv.cph)

But not sure what the output mean:

bootcov(mv.cph)
Cox Proportional Hazards Model

 cph(formula = Surv(as.numeric(Time), as.numeric(Status)) ~ df$miRNA, 
     data = as.data.frame((df)), x = T, y = T)
