[R] survival aareg plot problem

[Troels Ring]

Dear friends - I'm on windows 7, R 2.15.2

when I run the example for aareg in survival package I see this:

  plot(lfit[4], ylim=c(-4,4))
error in xy.coords(x, y, xlabel, ylabel, log) :
   'x' is a list, but does not have components 'x' and 'y'

Is that a matter of an old R?

Best wishes
