The original story was this (which I saw but lacked the time to analyze):
y<-coxph(Surv(time,status) ~ sex + ns(thickness,df=4),data=men)
z<-coxph(Surv(time,status) ~ ns(thickness,df=4),data=men)
termplot(z) # Prints a ? prompt (from parse(text=nmt) w/nmt==NULL)
termplot(y,terms=2) # Same
This can still be seen with the current devel version.
