What about the 'colClasses' or 'dateTimeAs' argument in 'read.xls' which gives back an iso-date-time character string. Or you could use the 'dateTimeToStr' function to convert the date number to a character string formatted as indicated. As a question: would additional entries (e.g.) 'posixctdatetime' and/or 'chrondatetime' for the 'colClasses' argument be useful? -- Regards, Hans-Peter ______________________________________________ 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.
