Using Thomas Lumley's solution with the lung dataset, I obtained:

curve(pweibull(x, scale=1/coef(lung.wbs), shape=1/lung.wbs$scale,
     lower.tail=FALSE),from=0, to=max(lung$time))


That's because you read the part of the message where I got the reparametrization wrong, rather than the part where I got right.


It should be
 curve(pweibull(x, scale=exp(coef(lung.wbs)), shape=1/lung.wbs$scale,
      lower.tail=FALSE),from=0, to=max(lung$time))
