Thank you.

But the problem with the "relsurv" package remains: when I try to use the
function "rsmul" following the package example, it give me an error
(Error in nrow(x) : object "x" not found).
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.
There are perhaps others packages to fit relative survival models ?

For the second question, try something like:

strptime('12/4/1996','%M/%d/%Y')
[1] "1996-09-04 00:12:00"
# only date?
as.Date(strptime('12/4/1996','%M/%d/%Y'))
[1] "1996-09-04"
Why not

as.Date('12/4/1996', format = '%m/%d/%Y')
[1] "1996-12-04"

? (And note the typo in your solution and hence incorrect answer.)

Dear R-users,

I have a couple of questions about the relsurv package:

1) when I try to run the example:

fit <-rsmul(Surv(time,cens)~sex+as.factor(agegr)+ratetable(age=age*365.24,sex=sex,year
=year),ratetable=slopop,data=rdata)
with the datasets in the package (rdata and slopop) it gives me an
error:
Error in nrow(x) : object "x" not found

2)
If I have a date format like:"6/17/1997 " "9/10/1990 " "12/4/1996 "
how
to convert it in the Rdate format required by ratetable?

Thank you very much for help,

Giulia
