Probably a bug plotting chron objects in xts. Either pot it with zoo or use POSIXct and plot it with xts: plot(z$C) # or z <- read.zoo(textConnection(Lines), header = TRUE, index = list(1, 2), FUN = function(...) as.POSIXct(paste(...), format = "%m/%d/%Y %H:%M")) x <- as.xts(z) plot(x) -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
