package relsurv
Dear R-Users,
I've recently used relsurv package for relative survival analysis. In particular I've tried to reproduce the examples proposed in the R-documentation about rsadd, rsmul and rstrans functions in R latest version (R 2.14.1). These examples don't run and the error message is always the following:

survexp ratetables for european contries?
Dear All,
Does someone have, or know of survexp ratetables for european contries,
especially Austria and Germany?
I know only about slopop in the package relsurv.
Thanks in advance

datadist options error, DESIGN library
Hello,
using the Design library, and the following command (from the Harrell's book, example at Ch.20):
dd <- datadist(rx, age, wt, pf, pf.coded, heart, map, hg, sz, sg, ap, bm)
options(datadist=='dd')
I get the following error:
Error in datadist == "dd" : comparison (1) possible only for atomic data or list
What does it means?
thank you,

survexp - example produces error
Dear All,
reposting, because I did not find a solution, maybe someone could
check the example below.
It's taken from the help page of survdiff. Executing it, gives the error
"Error in floor(temp) : Non-numeric argument to mathematical function"
best regards,

survexp with weights
Hello,
I probably have a syntax error in trying to generate an expected
survival curve from a weighted cox model, but I can't see it. I used
the help sample code to generate a weighted model, with the addition
of a "weights=albumin" argument (I only chose albumin because it had
no missing values, not because of any real relevance). Below are my
code with the resulting error

Survival: pyears and ratetable: expected events
Dear all,
I am having a (really) hard time getting pyears to work together with a
ratetable to give me the number of expected events (deaths).
I have the following data:
dos, date of surgery, as.Date
dof, date of last follow-up, as.Date
dos, date of surgery, as.Date
sex, gender, as.factor (female,male)
ev, event(death), 0= censored at time point dof, 1=death at time point dof

further notes on model.frame issue
This is a follow-up on my note of Saturday. Let me start with two important
clarifications
- I think this would be a nice addition, but I've had exactly one use for it
in the 15+ years of developing the survival package.
- I have a work around for the current case.
Prioritize accordingly.
The ideal would be to change survexp as follows:
fit <- survexp( ~ gender,

hazard ratio of interaction Cox model
Dear Forum,
I have a question about interaction estimate in the Cox model:
why the hazard ratio of the interaction is not produced in the summary of the model?
(Instead, the estimate of the coefficient is given in the print of the model.)

modINT <-cph( Surv(T_BASE, T_FIN,STATUS)~ NYHA + ASINI + RFP + FE_REC + XX_PR*XX_DISF)

Bayesian Relative Survival Analysis in R?
Hi all,
May i know does R has packages or code to run "Bayesian Relative Survival Analysis"? I have look through Bayesian Survival Analysis(2001) by Joseph George Ibrahim<http://www.google.com/search?tbo=p&tbm=bks&q=inauthor:%22Joseph+George+Ibrahim%22>, Ming-Hui Chen<http://www.google.com/search?tbo=p&tbm=bks&q=inauthor:%22Ming-Hui+Chen%22>, Debajyoti

Evaluation puzzle
The survexp function can fail when called from another function. The "why" of
this has me baffled, however.
Here is a simple test case, using a very stripped down version of survexp:
survexp.test <- function(formula, data,
weights, subset, na.action, rmap,
times, cohort=TRUE, conditional=FALSE,
ratetable=survexp.us, scale=1, npoints, se.fit,

Changelog for the survival package
> Several changes in print.survfit, plot.survfit and seemingly in the structure

> Is there somewhere a documentation of these changes, besides the code itself?
I agree, the Changelog.09 file is not as comprehensive as one would like.
Specific comments:

model.frame problem
A few weeks ago I reported a problem with model.frame, whose root lay
in a formula expression "....+ ratetable(x1=x1, x2=x2, ....x100=x100)"
that was really long and caused model.frame to fail. Brian had some
indefinite ideas on what might need to change in the base code to handle
it.
In survival_2.36-1 the bit of code that generated the offending
expression has been changed (mostly

Possible update to survival
I got good feedback from the list about a scope issue, so I am coming back for more.
Prior issue: users who type survival::coxph(survival::Surv(time, status) ~ x1 + x2 + surv ival::strata(group), data=mydata)
This messes up the character string matching for strata, done via tt <- terms(formula, specials= ?strata?). The code runs, and gives the wrong answer (group is treated as an ordinary

survexp - unable to reproduce example
Dear All,
when I try to reproduce an example of survexp, taken from the help
page of survdiff, I receive the error message
"Error in floor(temp) : Non-numeric argument to mathematical function"
.
It seems to come from match.ratetable. I think, it has to do with
character variables in a ratetable.
I would be interested to know, if it works for others. With an older

model.frame deficiency
The model.frame function has trouble with a certain type of really long
formula. Here is a test:
tname <- paste('var', 1:50, sep='')
tmat <- matrix(rnorm(500), ncol=50, dimnames=list(NULL, tname))
tdata <- data.frame(tmat)
temp1 <- paste( paste(tname, tname, sep='='), collapse=', ')
temp2 <- paste("~1 + cbind(", temp1, ")")

using survexp and ratetable with coxph object that includes a factor term
Hello,
I'm attempting to use the ratetable argument to
survexp in the survival package. I use
the example from the ?survexp help page below,
and then slightly modify it to produce an error.

data(pbc)
#fit a model without any factors
pfit1 <- coxph(Surv(time, status > 0) ~ trt + log(bili) +
log(protime) + age + platelet, data=pbc)
