The quickest fix is to add cmprsk to the recommended list , and that's is an R-devel issue.

I do not understand why I am getting the following error message. Can
anybody help me with this? Thanks in advance.

Help on competing risk package cmprsk with time dependent covariate
Dear R users,
I d like to assess the effect of "treatment" covariate on a disease relapse risk with the package cmprsk.
However, the effect of this covariate on survival is time-dependent
(assessed with cox.zph): no significant effect during the first year of follow-up,
then after 1 year a favorable effect is observed on survival (step
function might be the correct way to say that ?).

crr - computationally singular
Dear R-help,
I'm very sorry to ask 2 questions in a week. I am using the package
'crr' and it does exactly what I need it to when I use the dataset a.
However, when I use dataset b I get the following error message:
Error in drop(.Call("La_dgesv", a, as.matrix(b), tol, PACKAGE = "base")) :

Competing Risks Regression with qualitative predictor with more than 2 categories
Hello,
I have a question regarding competing risk regression using cmprsk package (function crr()). I am using R2.9.1. How can I do to assess the effect of qualitative predictor (gg) with more than two categories (a,b,c) categorie c is the reference category. See above results, gg is considered like a ordered predictor !
Thank you for your help

using crr in cmprsk
Hi,
I need to fit model using crr, however my covariate is
categorical with 3 levels. I use
crr(time,status,agesplit,failcode=1,cencode=0) where
agesplit is defined as <20,21-29,>30 years, so it
takes 0, 1 or 2 for each patient. I hoped to get
estimated coefficients for the levels 1 and 2 w.r.t
level 0 as in coxph. But, I didn't. Could someone
please help me to use crr in this

Competing risks adjusted for covariates
Dear R-users
Has anybody implemented a function/package that will compute an individual's risk of an event in the presence of competing risks, adjusted for the individual's covariates?
The only thing that seems to come close is the cuminc function from cmprsk package, but I would like to adjust for more than one covariate (it allows you to stratify by a single grouping vector).

Competing risks Kalbfleisch & Prentice method
Dear R users
I would like to calculate the Cumulative incidence for an event
adjusting for competing risks and adjusting for covariates. One way to
do this in R is to use the cmprsk package, function crr. This uses the
Fine & Gray regression model. However, a simpler and more classical
approach would be to implement the Kalbfleisch & Prentice method (1980,
p 169), where one fits cause

Plot of Fine and Gray model
Dear all,
Happy New year!
I have used the 'crr' function to fit the 'proportional subdistribution
hazards' regression model described in Fine and Gray (1999).
dat1 is a three column dataset where:
- ccr is the time to event variable
- Crcens is an indicator variable equal to 0 if the event was achieved, 1
if the event wasn't acheived due to death or 2 if the event wasn't

controlling axes in plot.cuminc (cmprsk library)
Dear R-help list members,
I am trying to create my own axes when plotting a cumulative incidence
curve using the plot.cuminc function in the CMPRSK library. The default
x-axis places tick marks and labels at 0, 20, 40, 60, and 80 (my data has
an upper limit of 96), whereas I want them at my own specified locations.
Here is my example code:

Fractional Polynomials in Competing Risks setting
Dear All,
I have analysed time to event data for continuous variables by
considering the multivariable fractional polynomial (MFP) model and
comparing this to the untransformed and log transformed model to
determine which transformation, if any, is best. This was possible as
the Cox model was the underlying model. However, I am now at the
situation where the assumption that the competing risks

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?

speed up crr function in cmprsk package
I am trying to use the crr function in the cmprsk package to analyze a large
patient dataset (45000 +), The model has 100 + covariates and 5 competing
risks. I am finding that R seems to get bogged down and even if I let it run
for several hours I don't get anything back. Am I expecting too much, or are
there ways to speed up the process? Any help is appreciated.
Best,

competing risks regression
Dear R users,
I used crr function in R package 'cmprsk' to fit a competing risks
model. There were no any error or
warning messages during running the function, but the output was obvious
not correct.
I saved the model fit as an object called f.crr. I extracted bfitj from
the object by doing f.crr$bfitj, and found
values of bfitj were extremely large (around 1e+138). I tried all

Pesos en modelos mixtos
Hola a todos,
Me gustaria saber si en un modelo mixto se puede usar el tamaño de muestra como
peso o es incorrecto hacerlo.
Por ejemplo en el comando 'lmer' del paquete lme4 hay una opcion 'weights'
(igual que en 'lm' de stats). Si tengo datos de una medida (por ejemplo el
peso) de 10 especies de aves (rango, de 50 a 3000 datos segun la especie) ¿puedo

SAS code in R
Dear all,
I was wondering if anyone can help? I am an R user but recently I have resorted to SAS to calculate the probability of the event (and the associated confidence interval) for the Cox model with combinations of risk factors. For example, suppose I have a Cox model with two binary variables, one for gender and one for treatment, I wish to calculate the probability of survival for the
