[R] 'col'-parameter in 'hist.POSIXt'

[Sebastian Meyer]

Hi guys.

The 'col'-parameter in the 'hist'-method for the classes 'POSIXt' and
'date' does not perform as it does in the default 'hist'-method.
Unfortunately, it does not only change the filling color of the boxes,
but also the color of the axislines.
[Using 'graphics'-package version 2.2.0]

Examples:
	
	# with POSIXct-object
	hist(.leap.seconds, "years", freq = TRUE, col="lightgrey")
	
	# with dates
	random.dates <- as.Date("2001/1/1") + 70*runif(100)
	hist(random.dates, "weeks", format = "%d %b", col="lightgrey")


Is that a bug?

Thanks in advance.

	Wastl
