chron command

Dear s-newsers

 

I'd be grateful for some help with the following problem (which may be very small!!) . I am using splus2000 for windows.

 

I am trying to create date & time objects so that I can use them later for sorting by date/time and to make comparisons of date/time. I have done the following so far, and as you can see only the dates printed out (and not the times) after using chron so I am not sure what it's done with the time. (Note my main file contains a few thousand records not just 20)

 

tempdate<-   as.character(testgp[,2])

temptime<-   as.character(testgp[,3])

nudates<-     chron(dates=tempdate,times=temptime,format=c("dd/mm/yyyy","hh:mm:ss"))
> nudates

Very many thanks for any suggestions
