my.syndromicD <- raw_to_syndromicD (id=lab.daily$SubmissionID,
                                  syndromes.var=lab.daily$Syndrome,
                                  dates.var=lab.daily$DateofSubmission,
                                  date.format="%d/%m/%Y")
## create a subset that ony includes the first 10 time points
