[R] restricted cubic spline in FGR function

[Raja, Dr. Edwin Amalraj]

Dear Thomas,

   I want to use evaluate effect of Age using restricted cubic form  in the  FGR function  as
Fgr.crr <- FGR(Hist(time, event) ~ rcs(Age_years), data=dat)

It provides error.  " Error in parse(text = termtext, keep.source = FALSE):  ....   1: response ~ rcs(Age_years

Do I need to change any of the R code?

Regards
Amalraj Raja
