Extra graphical arguments

[alexploner]

I have been using both plot.aalen and plot.cox.aalen for showing trajectories of cumulative residuals using score=1. While these plots do not receive the start.time /stop.time arguments, I have found that I can pass in an xlim-argument to limit the time range shown on the x-axis with plot.cox.aalen, but not with plot.aalen. Looking at the code, this seems to be because the extra graphical parameters available through ... are not passed on to plotScore in plot.aalen, while they are passed on in plot.cox.aalen.

Suggestion: add the extra ... to the call to plotScore (and incidentally also plot.cums) in plot.aalen for extra functionality and increased consistency at low cost.

Thanks for a great package, alexander
