Hello, I was hoping for advice regarding resolving the above error.
I have a csv file that contains the following variable: $ Order.Made.Date : Factor w/ 299 levels "1-Apr-08","1-Aug-05",..: 278 285 91 286 159 132 108 261 282 147 ... I want to calculate a variable named F.length, which is today's date minus the values contained in the variable: April$Order.Made.Date) I tried altering the date format but continued to receive the same error. > F.length <- difftime ("11/04/2008", April$Order.Made.Date) > Error in fromchar(as.character(x)) : character string is not in a standard unambiguous format > Order.date <- as.Date (April$Order.Made.Date) > Error in fromchar(x) : character string is not in a standard unambiguous format > Order.date <- 'as.POSIXlt' (April$Order.Made.Date) Error in fromchar(as.character(x)) : character string is not in a standard unambiguous format Any suggestions are appreciated, Bob ______________________________________________ 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.
