R devel - Oct 2007 - Unwanted axis labels when rug() has POSIXlt argument (PR#10380)

rug() may add integer axis labels when called with a POSIXlt object
as argument.

dtimes <- c("09/29/2007  12:54", "09/30/2007  00:14",
"10/01/2007
00:14",
               "10/02/2007  00:14", "10/03/2007  00:14",
"10/04/2007
00:14",
               "10/05/2007  00:14", "10/06/2007  00:14",
"10/07/2007
00:14",
               "10/08/2007  00:14")
z <- strptime(dtimes, "%m/%d/%Y %H:%M", tz="EST5EDT")
plot(z, rnorm(10))
rug(z)

This happens also undo Windows, both with 2.6.0 and 2.7.0 (2007-10-26

rug() is documented to require a numeric vector as input, and z isn't 
one of those, so there's an argument that this is user error.  Still, 
its behaviour is a little surprising.

The workaround is to use rug(as.numeric(z)).
