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

coxph and survfit issue - strata
Dear users, In a study with recurrent events: My objective is to get estimates of survival (obtained through a Cox model) by rank of recurrence and by treatment group. With the following code (corresponding to a model with a global effect of the treatment=rx), I get no error and manage to obtain what I want : data<-(bladder)

Small enhancement for CMD check
It would be nice if the 00check.log file also included this part of the output: Running ?bladder.R? Comparing ?bladder.Rout? to ?bladder.Rout.save? ... OK Running ?book1.R?

rpart - interpretation of results of tree on survival data
Hi All, I am fitting a tree to censored survival data using the rpart package and wanted to better understand the results. I am trying to interpret the output from the tree. I am interested in understanding what "yval" is for a survival tree. I see in the output of summary, the phrase "estimated rate". The estimated rate is 1 for the entire tree, and more of less for each

Changing CRAN package compile option defaults?
Is there an easy way to override the compile options when installing packages from CRAN on Unix-style systems? I tried setting CFLAGS, CXXFLAGS, and FFLAGS but they are not picked up. For example (with a random package and adding -mtune only to try to get rid of the default) export CFLAGS="-march=native -mtune=native" export CXXFLAGS="-march=native -mtune=native" R CMD

puzzled by math on date-time objects
Hi, I don't understand the following.

Looks like a bug in subsetting of a complicated object
I don't understand what is happening! I have a (large) object sim1, an matrix list with dim c(101,101) where each element is an 3*3 matrix. I am subsetting that with a matrix coo, of dim c(100,2), of unique indices, but the resulting object has length 99, not 100 as expected. Code reproducing the problem follows: library(RandomFields) set.seed(123) sim0 <- GaussRF(x=seq(0, 100, by=1),
