R help - Mar 2018 - restricted cubic spline in FGR function

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

the problem is not in my package. you can probably see this with tracebach()

rcs is from rms and FGR is just a wrapper for cmprsk

it would be nice though to fix this and if you can I would be very happy
to include your contribution in my package.
