[R] MASS4 page 360 cumulative hazard plot

[Ross Darnell]

I cannot reproduce Fig. 13.2 in MASS4.

> plot(gehan.surv,fun='cloglog')
Warning message:
2 x values <= 0 omitted from logarithmic plot in: xy.coords(x, y, 
xlabel, ylabel, log)

and the x-axis is badly scaled.

I was wondering if someone can help
