Now, I tried the same experiment on my Solaris2.4 system, with exactly the same R-survival4 setup, and got: > library(survival4) Autoloading required package: splines > coxph(Surv(c(1,2,3,4), c(1,1,1,1)) ~ c(1,0,1,0)) 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?
