R help - Oct 2014 - Default Display of hist.Date with breaks="months"

Hi all,

The default display of random dates with breaks="months" is less than
optimal.

set.seed(20141024)
random.dates <- as.Date("2001/1/1") + round(365*stats::runif(100))
hist(random.dates, "months")

The 13 edges of the 12 bars are labelled "Dec", "Jan",
"Feb", ..., "Nov", "Dec".
The first bar represents the number of days in January, the label on the RIGHT
edge of the bar.

It is clear what is happening if the format is changed.

hist(random.dates, "months", format = "%d %b", las=2)

The labels are now "Dec 31", "Jan 31", "Feb 28",
....  which isn't intuitive to me.

I'd rather have this as the default behavior (but without having to
explicitly create the breaks)

hist(random.dates,
breaks=as.Date(c(paste("2001",1:12,"1",sep="/"),
"2002/1/1")), right=FALSE)
hist(random.dates,
breaks=as.Date(c(paste("2001",1:12,"1",sep="/"),
"2002/1/1")), right=FALSE, format = "%d %b", las=2)

I guess none of that is a question.  Have a nice weekend.

Chris
