Dear all,
I am using Windows and R 2.9.2 for my analyses. I have a large dataset and
I am particularly interested in looking at time to an event for a continuous
variable. I would like to produce a plot of log(relative risk) or relative
risk (also known as hazard ratio) against the continuous variable.
I have spent a long time looking for advice on how to do this but my search
has proved fruitless - sorry if I've missed something obvious. It seems
that there are options such as muhaz, survfit, coxph and cph that may enable
some plots to be produced but none that specifically look at the relative
risk one.
In addition to the survival analysis, I have incorporated the mfp function
(from package mfp).
I currently use code such as,
library(mfp)
library(Design)
coxfit1 <- coxph(Surv(rtime,rcens)~cts,data=data1)
or
coxfit2 <-
mfp(Surv(rtime,rcens)~fp(cts),family=cox,data=data1,select=0.05,verbose=TRUE)
plot(coxfit1) nor plot(coxfit2) produce the relevant relative risk vs.
continuous variable that I need.
Can anyone help?
Thank you,
Laura
