Sorry for the misdirection, I see now that you are describing survreg()
not coxph().
But even coxph() seems to barf on this.
A possible workaround:

I apologise for not including a reproducible example with this query but I
hope that I can make things clear without one.
I am fitting some finite mixture models to data. Each mixture component

I want to install hdf5 libraries for R and I get the same error as posted

However, in my defense, I thought simply how to recover the specific numbers
that Kevin wants to get.
I don't understand why R doesn't output a value for F and Pr for the
Error (Block) dimension, as my textbook shows 12.807 and 0.0015
respectively.

I'm trying to find a way to create dummy variables from factors in a
