Hi there,

Here is a record of an R session:
Autoloading required package: splines
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.

Hmm.  I have

hornik at pc25:~$ uname -a
Linux pc25 2.0.30 #8 Thu Aug 28 01:02:50 CEST 1997 i586 unknown

and get

R> library(survival4)
Autoloading required package: splines 
R> coxph(Surv(c(1,2,3,4), c(1,1,1,1)) ~ c(1,0,1,0))
Call:
coxph(formula = Surv(c(1, 2, 3, 4), c(1, 1, 1, 1)) ~ c(1, 0, 
        1, 0))


              coef exp(coef) se(coef)     z    p
c(1, 0, 1, 0) 0.94      2.56     1.24 0.758 0.45

Likelihood ratio test=0.62  on 1 df, p=0.432  n= 4 

with 0.60.1 and a few patches, so perhaps you should wait for 0.60.2 (or
0.61?) to be out shortly ...

-k

PS.  Btw, which version of survival4 is it?

Kurt,

I use survival4_1.0-2. Now, I tried the same experiment on my
Solaris2.4 system, with exactly the same R-survival4 setup, and
got:
Autoloading required package: splines
ld.so.1: /export/home1/local/R-0.60.1/bin/R.binary: fatal: relocation
error: symbol not found: S_alloc: referenced in
/export/home1/local/R-0.60.1/library/survival4/libs/survival4.so
Killed

which, besides ???, leads me to a question about S_alloc:
I haven't found any documentation about the proper way to
allocate/free memory in user-supplied C functions. I have 
used the standard C routines malloc and free. It works, but my
functions are very slow when run under R, compared to when called
from a standalone main program. Any suggestions?
