[R] Porting plotterm() & gamterms() from s-plus

I'm trying to plot pspline'd explanatory variables from coxph() models as per Therneau and Grambsch (Modeling Survival Data: Extending the Cox Model). They have s-plus functions for this at:

http://www.mayo.edu/hsr/people/therneau/book/sfunction/gamterms.s http://www.mayo.edu/hsr/people/therneau/book/sfunction/plotterm.s

I'd like to make these plots in R, but they make use of non-R functions, and I'm not sure how to adapt gamterms and plotterm to R. Have others done this, or does anyone have advice?

Thanks,
