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 Stephen I can provide data - I am doing a dry run to see if there is something glaringly obvious that I am missing -- Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods. We are mammals, and have not exhausted the annoying little problems of being mammals. -K.
