Dear all, according to the Help-page of DateTimeClasses {base} I should be able to do
time - z with time date-time objects z a numeric vector (in seconds) or an object of class "difftime". However, on R version 2.6.0 (Windows XP) I get > Sys.time() - as.difftime(c("0:3:20", "11:23:15")) Time differences in mins [1] 1191837998 1191837318 attr(,"tzone") [1] "" Warning message: Incompatible methods ("-.POSIXt", "Ops.difftime") for "-" This works, on the other hand: > Sys.time() - as.numeric(as.difftime(c("0:3:20", "11:23:15"))) [1] "2007-10-08 12:16:18 Westeuropäische Normalzeit" "2007-10-08 12:04:58 Westeuropäische Normalzeit" Am I understanding something wrongly? Many thanks and best regards, Stefan ____________________________________ Dr. Stefan Albrecht, CFA Allianz Private Equity Partners GmbH Königinstr. 19 | 80539 Munich | Germany Phone: +49.(0)89.3800.18317 Fax: +49.(0)89.3800.818317 EMail: [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> Web: www.apep.com <http://www.apep.com/> Allianz Private Equity Partners GmbH | Geschäftsführung: Wan Ching Ang, Karl Ralf Jung Sitz der Gesellschaft: München | Registergericht: München HRB 126221 | Ust-ID-Nr.: DE 813 264 786 ______________________________________________ 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.
