error message in cox regression cph()
...know I could have used coxph() instead, but I'd like to predict the outcome on another dataset and coxph() does not allow for interaction terms...
I hope anyone can help me here. Underneath is the code I used for my data, if it's of any use...
Thanks, cheers Roel

Error: expected the collection operator c error pos 98 (error on line 1)
...model with a cohort size N=1. I output the simulation data using bugsdata(data), where data is the following list.
> data
$Dose
[1] 140
$Y
[1] 0
bugsdata(data) puts out the file data.txt as follows.
list(Dose=1.40000E+02, Y=0.00000E+00)
after I type the following line
modelData("data.txt") # read data file
I get the ERROR:

If I rewrite the file
list(Dose=c(1.40000E+02), c(Y=0.00000E+00))
it runs fine. Can you suggest a way to get the output dataset to automatically p...

Error from Brugs "'r for windows gui front-end has stopped working''
Dear all,
I just try to run the example in R brugs packages, but not only once. Loop is added in this example. After several times (7, 11, or other random number), there is an error message "r for windows gui front-end has stopped working". This happened in two laptops with windows 7 and vista. I have tried different versions of R (2.14.1 and 2.13) and Brugs packages (0.7.1 and 0.7-5).

R, Coda, and OpenBUGS
Hi All,
I am trying to figure out how to use R-Coda with the output from
OpenBugs. I have installed and loaded the packages BRugs and R2WinBUGS.
I have successfully run a simple Bayes model in WinBUGS using R2WinBUGS'
"bugs" and have used "read.bugs" to build the coda object. I can
successfully switch to OpenBugs and run the same model and get the basic
summary
