[R] plot(cox.zph()): customize xlab & ylab

[Dan Bebber]

Hello,

plot(cox.zph(my.ph),var=1,xlab="Year")

gives the error:
Error in plot.default(range(xx), yr, type = "n", xlab
= "Time", ylab = ylab[i],  : formal argument "xlab"
matched by multiple actual arguments

How can I customize the xlab and ylab for plots of
cox.zph?

Thanks,
Dan Bebber
