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?

problems with postscript device
...f()
The result looks quite different compared to the X-windows version.
The symbol 1 (pch=1) is much to small, while the other symbols
seem to big.
Is it a bug? How can I work it around?

selectFGR vs weighted coxph for internal validation and calibration curve- competing risks model
...o. But I do not know how to do internal validation of the model and subsequently obtain calibration plot. Is it possible to use Wolbers et al Epid 2009 approach 9 (R code for internal validation and calibration) . It is possible to get these measures after using R function 'crr' or 'FGR'. That is why I wanted to go in that route. At the same time, I had this doubt because their approach assume a record per individual whereas weight coxph creates two or more records per individual. I am new to R and could not modify the R code easily. Any suggestion? Has anyone done inter...

Does anybody see a way to solve this problem?
Thanks for any suggestions!

P.S.: Similar problems with expression() can arise with producing

x_{} are quantiles, and p and q are chosen so that k=0 for the normal

generating a sequence
Hi everyone
I'm trying to generate a vector of the form
a <- c(1,2,3,4,1,2,3,1,2,1) where n = 5
in a general way, where n can be any positive integer.
I've run out of ideas. Does anyone have any suggestions?
Thanks
