The problem is that since there is a space between the date and time and you are also using a space to separate fields the file has become inconsistent. It would be better to write it out as a csv file so that the date and time remain as a single field. If its too late for that then you can still recover it but its a bit more work. First get the column names and then read everything but the header adding the column names yourself like this: library(zoo) File <- "test2.txt" cn <- c("Date", read.table(File, nrow = 1, as.is = TRUE)) z <- read.zoo(File, header = FALSE, skip = 1, index = 1:2, tz = "", col.names = cn) -- 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.
