What did the maintainer say when you asked (see the posting guide)?

You didn't give a reproducible example: here is my attempt to make 
yours reproducible in a legible way):

library(relsurv)
data(rdata); data(slopop)
fit <-rsmul(Surv(time,cens) ~ sex + as.factor(agegr) +
             ratetable(age=age*365.24,sex=sex,year=year),
             ratetable = slopop, data = rdata)

And that works in

> sessionInfo()
R version 2.7.2 (2008-08-25)
x86_64-unknown-linux-gnu

locale:
LC_CTYPE=en_GB.UTF-8;LC_NUMERIC=C;LC_TIME=en_GB.UTF-8;LC_COLLATE=C;LC_MONETARY=C;LC_MESSAGES=en_GB.UTF-8;LC_PAPER=en_GB.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=en_GB.UTF-8;LC_IDENTIFICATION=C

attached base packages:
[1] splines   stats     graphics  grDevices utils     datasets  methods
[8] base

other attached packages:
[1] relsurv_1.4     survival_2.34-1

loaded via a namespace (and not attached):
[1] tools_2.7.2

So, please do follow the posting guide: it looks like the problem is local 
to you.
