[R] times

[thoeb]

Hi! I have an input table with a column "Dates" in the format
"month/day/year" (eg. "5/11/1999" and a column "Times" in the format
"hours/minutes" (eg. "15:20"). In R I need to convert them into chron
objects to extract colums only containing months, days, minutes, ..

For the dates it is no problem if I write:
dmy.lwc<-chron(dates=lwc.file[,1],format=(dates="m/d/y"))

But it does not work the same way for the times if I write:
hm.lwc<-chron(times=lwc.file[,2],format=(times="h:m"))

Error-Message: Error in convert.times(times., fmt) : format h:m may be
incorrect
In addition: Warning message:
In is.na(out$s) : is.na() applied to non-(list or vector) of type 'NULL'

Why should the format "h:m" not be correct?
