[R] Chron format question h:m not working

[arun]

HI Stephen,

I am using R 3.0.0.   The responses in an old thread (http://r.789695.n4.nabble.com/times-td3016621.html), suggests  some solutions, but not the one you are looking for. 

A.K.

Thanks for the quick replies.  I have this working with a similar suggestion to what arun suggests.  I am just interested in why the option to use just h:m isn't supported.

#re: Jeff

chron(dates.="2009/05/01", times.="15:00:00", format=c(dates=c("y/m/d"), times="h:m:s"))
chron(dates.="2009/05/01", times.="15:00", format=c(dates=c("y/m/d"), times="h:m"))


same outcome. 


Does updating to R 3.0.0 solve the problem?


Thanks for all of the help.


Stephen
