The word "secs" appears in "Run time: 1.960625 secs" because you put it there in your cat() statement. It has nothing to do with the number itself.
Simply try typing end.time - begin.time at the prompt, and see what you get. Then see ?difftime for more information. Example difftime(end.time,begin.time,units='hours') To get the interval formatted as "1 day, 23 hours, x minutes, x seconds" you will have to do more work. -Don At 4:18 PM +0200 10/26/05, Muhammad Subianto wrote: >Dear all, >I have ran a simulation in R. >This simulation was running about at least two days. >Here is below the result some part of my code about time result. >I don't understand about > >Start time: Mon Oct 24, 2005 at 04:23:01 PM > Finish time: Wed Oct 26, 2005 at 03:26:19 PM > Run time: 1.960625 secs. > >This is about two seconds or one day and nine hours? >Then, how could I convert to 1 day, 23 hours, ? minutes, ? seconds. >Thanks you very much for any suggestions. > >Best wishes, Muhammad Subianto > > > >################################################################################ > > # Begin of program and timestamp: > > cat(format(begin.time <- Sys.time(), "%a %b %d %X %Y") ,"\n") >Mon Oct 24 04:23:01 PM 2005 > > cat("Start time:", secs <- format(begin.time, "%X"), "\n") >Start time: 04:23:01 PM > > cat("Sys.time:", begin.time <- Sys.time(), '\n') >Sys.time: 1130163781 > > > > >--- CODE SIMULATION --- > > > > # End of program and timestamp: > > cat("Sys.time:",end.time <- Sys.time(), '\n') >Sys.time: 1130333179 > > cat("Run Time:",end.time-begin.time, 'secs.\n\n') >Run Time: 1.960625 secs. > > > cat("Finish time:", secs <- format(end.time, "%X"), "\n") >Finish time: 03:26:19 PM > > cat(format(end.time <- Sys.time(), "%a %b %d %X %Y") ,"\n") >Wed Oct 26 03:26:19 PM 2005 > > > > cat("\n", >+ " Start time:", secs <- format(begin.time, "%a %b %d, %Y at >%X"), "\n", >+ "Finish time:", secs <- format(end.time, "%a %b %d, %Y at >%X"), "\n", >+ " Run time:", end.time-begin.time, 'secs.\n\n') > > Start time: Mon Oct 24, 2005 at 04:23:01 PM > Finish time: Wed Oct 26, 2005 at 03:26:19 PM > Run time: 1.960625 secs. > > > >########################################################################### > >______________________________________________ >R-help@stat.math.ethz.ch mailing list >https://stat.ethz.ch/mailman/listinfo/r-help >PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html -- -------------------------------------- Don MacQueen Environmental Protection Department Lawrence Livermore National Laboratory Livermore, CA, USA ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
