Hi there, Here is a record of an R session: > library(survival4) Autoloading required package: splines > coxph(Surv(c(1,2,3,4), c(1,1,1,1)) ~ c(1,0,1,0)) Error in .C("coxfit2", iter = as.integer(iter.max), as.integer(n), as.integer(nvar), : C/Fortran function not in load table Why is "coxfit2" not in the load table? How do I fix it? System is Linux. Goran -------------------------------------------------------------------- Goran Brostrom...

Full_Name: Jerome Asselin Version: 1.6.1 OS: RedHat Linux 7.2 Submission from: (NULL) (142.103.173.179) Hello, I get a segmentation fault when I run the following code. I wouldn't expect meaningful results because my response variable contains only missing values. However, I would expect something like a regular error (not a segmentation fault). library(survival) data <-

...some plots to be produced but none that specifically look at the relative risk one. In addition to the survival analysis, I have incorporated the mfp function (from package mfp). I currently use code such as, library(mfp) library(Design) coxfit1 <- coxph(Surv(rtime,rcens)~cts,data=data1) or coxfit2 <- mfp(Surv(rtime,rcens)~fp(cts),family=cox,data=data1,select=0.05,verbose=TRUE) plot(coxfit1) nor plot(coxfit2) produce the relevant relative risk vs. continuous variable that I need. Can anyone help? Thank you, Laura [[alternative HTML version deleted]]

I'm looking at memory efficiency for some of the survival code. The following fragment appears in coxph.fit coxfit <- .C("coxfit2", iter=as.integer(maxiter), as.integer(n), as.integer(nvar), stime, sstat, x= x[sorted,] , ... Does this make a second copy of x to pass to the routine (my expectation) or will I end up with 3: x and x[sorted,]...

...is quite different results, with the result with version 2.6.1 being the most reasonable. But if I for instance do a cox-regression on on the same data with the same covariate with the two different versions I do get the same result, which is how it should be R version 2.6.1 (2007-11-26): print(coxfit2) Call: coxph(formula = Surv(levetid, status == 2) ~ malder + faar + gest + vekt.ind, data = ord.mfr) coef exp(coef) se(coef) z p malder -0.046320 0.955 0.00972 -4.767 1.9e-06 faar -0.040658 0.960 0.00639 -6.367 1.9e-10 gest -0.000211 1.000 0.0...

Dear R-help, Let me know if I should email r-devel instead of this list. This message is addressed to Professor Lumley or anyone familiar with the survey package. Does svycoxph() implement the method outlined in Binder 1992 as referenced in the help file? That is, are weights incorporated in the ratio term (numerator and denominator) of the estimating equation? I don't believe so since
