I have a matrix with data that runs from 1/1/06 00:01:00-1/31/08 23:46:00.
I have read in the data with this

fmt.chron <- function(x) {
   chron(sub(" .*", "", x), gsub(".* (.*)", "\\1:00", x))
}

x <- read.zoo(file.choose(), sep=",", header=T, FUN=fmt.chron)

plotted with this
plot(x[,(seq(3, by=9, length.out=12))], xlim=c(chron("9/01/2006",
"00:01:00"), chron("1/31/2007", "12:46:00")))

and I was excited to be able to plot subsets with date and it worked it
worked fine until I put in the above and the axis displays 9/09, but still
seems to plot the data when I change the xlim.
Thank you very much

I can provide data - I am doing a dry run to see if there is something
glaringly obvious that I am missing
