The package maintainer may be able to give help. However, I don't get the same output as you (3.1.2). Perhaps you can update and solve your problem.

I have some problems with the package “survMisc”. When I am loading it I am getting the following > library(survMisc) Loading required package: survival Loading required package: splines Loading required package: km.ci Loading required package: ggplot2 Loading required package: data.table data.table 1.9.4 For help type: ?data.table *** NB: by=.EACHI is now explicit. See README to restore previous behaviour. Loading required package: gridExtra Loading required package: grid Loading required package: rpart Attaching package: ‘survMisc’ The following objects are masked from ‘package:stats’: AIC, BIC, median, quantile In the above output I noticed the line with the three stars (*). In order to restore the data.table in its previous behavior I tried to locate the README file but I couldn’t. I ignored that NB in the previous output and I continue to run the example given in the above mentioned package for the routine comp(). The commands and the output are given below. > ### 2 curves > data(kidney,package="KMsurv") > s1 <- survfit(Surv(time=time, event=delta) ~ type, data=kidney ) > comp(s1) $tne t n e n_type=1 e_type=1 n_type=2 e_type=2 1: 1.5 86 2 43 1 43 1 2: 3.5 80 2 40 1 40 1 3: 4.5 72 4 36 2 36 2 4: 5.5 66 2 33 1 33 1 5: 8.5 60 4 30 2 30 2 6: 9.5 54 2 27 1 27 1 7: 10.5 50 2 25 1 25 1 8: 11.5 44 2 22 1 22 1 9: 15.5 28 4 14 2 14 2 10: 16.5 26 2 13 1 13 1 11: 18.5 22 2 11 1 11 1 12: 23.5 8 2 4 1 4 1 13: 26.5 6 2 3 1 3 1 $tests $tests$lrTests ChiSq df p Log-rank 0 1 1 Gehan-Breslow (mod~ Wilcoxon) 0 1 1 Tarone-Ware 0 1 1 Peto-Peto 0 1 1 Mod~ Peto-Peto (Andersen) 0 1 1 Flem~-Harr~ with p=1, q=1 0 1 1 $tests$supTests Q p Log-rank 0 1 Gehan-Breslow (mod~ Wilcoxon) 0 1 Tarone-Ware 0 1 Peto-Peto 0 1 Mod~ Peto-Peto (Andersen) 0 1 Renyi Flem~-Harr~ with p=1, q=1 0 1 Notice the zeros (0) that corresponds to the test statistics. (To my opinion those zeros are strongly related to the NB above). Next I noticed the following strange, to my opinion, thing. More precisely I have written the following routine proc<-function(){ rm(list=ls()) library(survMisc) d<-read.table("C:\\Program Files\\R\\Data\\Survival\\HosmLem.txt",fill=TRUE,header=TRUE) d4<-as.factor(d[,4]) s<-survfit(Surv(d[,2], d[,5])~d4) ctest<-comp(s)$tests print(ctest) } The data used are those of Hosmer and Lemeshow book on Applied Survival Analysis.
