HI, One possible way would be to use paste() chron(times.=paste0("15:00",":00"),format=c(times="h:m:s")) #[1] 15:00:00
#or you could use library(lubridate) hm("15:00") #[1] "15H 0M 0S" A.K. ----- Original Message ----- From: Stephen Sefick <sas0...@auburn.edu> To: "r-help@r-project.org" <r-help@r-project.org> Cc: Sent: Wednesday, May 1, 2013 12:28 PM Subject: [R] Chron format question h:m not working R 2.12.2 on Scientific Linux 6.4 #works chron(times.="15:00:00", format=c(times="h:m:s")) #doesn't work chron(times.="15:00", format=c(times="h:m")) >From chron Manual: The times format can be any permutation of "h", "m", and "s" separated by any one non-special character.
