Hi, Sorry, I didn't looked at the title. If you need to get the xts object Try this: dat1<-read.table(text=" reportDate total 1 2010-12-31 170609.2 2 2011-01-03 170778.0 3 2011-01-04 170748.4 4 2011-01-05 170599.5 5 2011-01-06 170335.0 6 2011-01-07 169842.1 ",sep="",header=TRUE,stringsAsFactors=FALSE) library(xts) dat2<-xts(dat1$total,order.by=as.POSIXct(dat1$reportDate,format="%Y-%m-%d")) str(dat2) #An ‘xts’ object from 2010-12-31 to 2011-01-07 containing: # Data: num [1:6, 1] 170609 170778 170748 170600 170335 ... #Indexed by objects of class: [POSIXct,POSIXt] TZ: #xts Attributes: #List of 2 # $ tclass: chr [1:2] "POSIXct" "POSIXt" # $ tzone : chr "" dat2 [,1] #2010-12-31 170609.2 #2011-01-03 170778.0 #2011-01-04 170748.4 #2011-01-05 170599.5 #2011-01-06 170335.0 #2011-01-07 169842.1 A.K.

I have pulled in data via RODBC into a data frame, which looks like below and I'm getting the same error message: /("Error in as.POSIXlt.character(x, tz, ...) : character string is not in a standard unambiguous format") / The date format seems pretty straightforward to me so I'm kind of stuck at what to do. BTW, I'm *very* new to R so please forgive some ignorance here reportDate total 1 2010-12-31 170609.2 2 2011-01-03 170778.0 3 2011-01-04 170748.4 4 2011-01-05 170599.5 5 2011-01-06 170335.0 6 2011-01-07 169842.1 -- View this message in context: http://r.789695.n4.nabble.com/as-xts-tp3028280p4646499.html Sent from the R help mailing list archive at Nabble.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. ______________________________________________ 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.
