Dear R users, I am trying to use "muhaz" and "plot.muhaz" functions in "muhaz" package to estimate and plot hazard funciton. However function "muhaz" always gives error message "Error in Surv(times, delta) : object "times" not found". I could not even run their sample codes in the user's manual as follows:
data(ovarian) attach(ovarian) fit1 <- muhaz(futime, fustat) it gave the same error message. By the way, the "survival" package is installed and functions well on my computer. Does anyone have the same problem? Thanks!
