This is fixed in version 2.37-8 of the survival package, which has been in my "send to
CRAN real-soon-now" queue for 6 months. Your note is a prod to get it done. I've been
updating and adding vignettes.

I am receiving the following error when trying to include both tt (time

Error in residuals.coxph(fit2, type = "dfbeta", collapse = cluster, weighted =
TRUE) :
Wrong length for 'collapse'
I tried both 64 bit (R.3.1.0) and 32 bit (R.3.1.2) in Windows 7 64bit and get
the same errors
Inclusion of tt and cluster terms worked fine in R2.9.2-2.15.1 under Windows
Vista 32 bit and Ubuntu 64 bit
Any ideas?
