Dear R
I am trying to understand and use the flexible parametric survival model
suggested by Royston and Parmar.
However I am stuck trying to plot the adjusted survival curves for
different covariates in the following code:
library(flexsurv)
library(graphics)
spl <- flexsurvspline(Surv(futime, fustat) ~ rx+ecog.ps+resid.ds+age, data
= ovarian, k=2, scale="odds")
spl
the code "plot(spl)" produces a red spline which is difficult for me to
interpret. I would like to plot survival based on for example age or rx.
Thanks in advance for your help in this matter
