[R] predicted survival curves from a Cox time dep model

Dear R users, is there a way to plot "predicted" curves from a Cox model with a time dependent covariates using "predict", in which other significant covariates are included with specific values ? I use cluster(id) in this time-dep. Cox model for rows belonging to the same patient, and this

Re: [R] predicted survival curves from a Cox time dep model

Calculating predicted survival curves in the case of a time dependent variable is a thorny problem; not computationally but conceptually. It is not always clear exactly what you WANT to plot. My book has a whole section on the subject, which is only to say that it is too long a subject to sum
