relsurv package
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

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 - 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"

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

I agree, the Changelog.09 file is not as comprehensive as one would like.

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,

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,

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

who submitted ratetables to CRAN?
Hi,
the ratetables package on CRAN contains no author/maintainer
information whatsoever and I cannot remember who submitted it
... is the creator out there on this list?
The DESCRIPTION file is missing (otherwise I wouldn't have problems
with finding the author) ...

survexp with large dataframes
Hello, and thank you in advance.
I would like to capture the expected survival from a coxph model for
subjects in an observational study with recurrent events, but the
survexp statement is failing due to memory. I am using R version
2.13.1 (2011-07-08) on Windows XP.
My objective is to plot the fitted survival with the Kaplan-Meier
plot. Below is the code with output and [unfortunately]

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

Expected number of events, Andersen-Gill model fit via coxph in package survival
Hello,
I am interested in producing the expected number of events, in a
recurring events setting. I am using the Andersen-Gill model, as fit
by the function "coxph" in the package "survival."
I need to produce expected numbers of events for a cohort,
cumulatively, at several fixed times. My ultimate goal is: To fit an
AG model to a reference sample, then use that fitted model

model.frame deficiency
The model.frame function has trouble with a certain type of really long
formula. Here is a test:

tdata <- data.frame(tmat)
temp1 <- paste( paste(tname, tname, sep='='), collapse=', ')

(survexp:) compute the expected remaining survival time

I would like to know if there is a direct method to compute the
expected remaining survival time for a subject having survived up to
time t. survexp gives me the probabilty for subject S to survive up to

heap memory exhausted
Hi
I always have following error message when I try to read
a big ascii-file:
> inzp<-read.data()
> Error: heap memory (1953 Kb) exhausted [needed 0 Kb more]
read.data() is a small function that reads the ascii-file.
When I cut the ascii-file to a small one I don't have this
problem.
Can I extend this 'heap memory' for reading big data files? How?

Bayesian Relative Survival Analysis in R?

May i know does R has packages or code to run "Bayesian Relative Survival Analysis"?

Hazard model with long-term survivor (cure model)
Dear All,
Are there R packages that can estimate survival model with long-term
survivors? This is sometimes known as "cure" model or "split-population"
model. Thanks.

irrelevant warning message
Context:
R version 2.7.1 (2008-06-23)
I don't know when this was upgraded in the department, I just ran into the
aberrent behavior today.
Problem:
Our group BY CHOICE does not change character variables into factors by
default. I can get into a long arguement as to why later, and will give one
example of why below.
The default behavior of S, Splus and R has been to create
