R help - May 2006 - plot problem in version 2.3.0 with dates as x

Hi, I have some old programs running well for older versions 2.2.0 and
2.1.1, but cannot run under 2.3.0.  The problem is in plot with dates as x:

library(survival)
test <- data.frame( x = c(1:20), date = as.date(1:20))
plot(test$date, test$x)
---------------------------------------------------------
Error in plot.window(xlim, ylim, log, asp, ...) :
        "log=" specification must be character

Is this a bug in v2.3.0?

Thanks,

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.

Using R 2.2.1 under Windows, I have developed a very busy Trellis dot plot
with 2 columns of 7 panels and dates on the x axes. Is there a way to print
the date labels vertically instead of horizontally so I can include more on
the graph? Also, can I take some control over which dates are printed (e.g.
1,4,7,10,13)? Nothing stood out to me on trellis.par.get().

Thanks for the help.

See the scales section in the help page for xyplot.  This gives you 
control over the number, location, and labeling of ticks as well as the 
rotation of the labels.
