Have just compiled and installed R-2.0.0.tar.gz running SuSE9.0.
The function vcov do not accept "coxph" object as input any longer.
The same R-program running R1.9.1 do work. R-program attached below.
Exporting the coxph object from R2.0.0 to R1.9.1 I get vcov ouput in R1.9.1.
Exporting the coxph object from R1.9.1 to R2.0.0 I get errors in R2.0.0
