[R] How to extract z value from coxph

[Man, Chris T.]

Hi all,

I have tried to use coxph to determine which variables are significant in survival analysis. I also would like to use their z scores as weights to build a linear classification model. Although the function outputs the z value, but I can't access to it, so that I can write code to extract them automatically and pass them to the next function. Can someone help?

Thanks,

Chris
