[R] plot problem in version 2.3.0 with dates as x

[Prof Brian Ripley]

Note, this is about plot.date (not dates, a different class) in the 
contributed survival package, not R 2.3.0.  You need to use log="" as 
plot.date incorrectly uses as its default log=NULL.

Please see the posting guide about how to report a problem in a 
contributed package.
