I have got these two columns (for example dose of a drug for a subject is the value): date1                                   date2                      value 05/10/2016                         06/10/2016               3 10/10/2016                         13/10/2016               5   05/10/2016 is day 0 06/10/2016 is day 1 07/10/2016 is day 2 08/10/2016 is day 3 09/10/2016 is day 4 10/10/2016 is day 5 and so on..   and between day 2 and day 4 the value is 0 so I would like to obtain for the subject an output like this:   start                       stop                 value 0                            1                       3 2                            4                       0 5                            9                       5   Thanks!! ...

Hi!   I have got a problem with dates and I do not know how to solve it!   I have got these two columns for example: date1                                   date2                      value 05/10/2016                         06/10/2016               3 10/10/2016                         13/10/2016               5   I would like to create a column start, a column stop in order to count the days since 5/10/2016 and the relative value:   start                       stop                 value 0                            1                       3 2                            4                       0 5                            9                       5   I really do not know if this is possible!   Thanks for your help     ...
