KM.plot {risksetROC} | R Documentation |
This function creates Kaplan-Meier plot.
KM.plot(Stime, survival, max.T=NULL, lty=NULL, all=TRUE, ...)
Stime |
unique ordered event times |
survival |
estimates of survival probabilities at Stime |
max.T |
maximum time to be considered for plotting, default is NULL which plots survival till max(Stime)+1 units |
lty |
line type |
all |
TRUE or FALSE, default is TRUE |
... |
additional plot arguments |
This function creates Kaplan-Meier plot. If all=TRUE, then this creates a new plot. If all=FALSE, it adds line to an existing plot and hence must be called after a plot() or similar call.
