    data rearrangement problem

    Hi all,

    I have a table of data that were generated during a scientific trial. The data describe the time (in days) at which an effect was observed in patients given a drug. My table looks like this:

    Days post administration Number of patients affected
    1 0
    2 1
    3 3
    4 1

    I need to rearrange this data to look at the patients as a population so that I can calculate the mean and standard deviation for the time at which they became affected. So I need a table that looks like this:

    Patient Affected on day
    1 2
    2 3
    3 3
    4 3
    5 4

    Any suggestions on how to perform this rearrangement would be much appreciated. I'm stumped.

    Re: data rearrangement problem

    I made the tables in the original post manually as examples. My real data set is obviously somewhat larger.

    It works like this:

    On day 1, 0 patients were affected
    On day 2, 1 patient was affected
    On day 3, 3 patients were affected
    On day 4, 1 patient was affected

    In other words:

    The first patient was affected on day 2
    The second, third and fourth patients were affected on day 3
    The fifth patient was affected on day 4

    There are only five patients and four days in the data set in this example.

    The numbers in column A of my second table are irrelevant. They could just as easily be letters, names or anything else to designate a unique identifier to each patient. E.g.

    patient affected on day
    Bob 2
    Fred 3
    Bill 3
    John 3
    Cletus 4

    It doesn't matter, I just need a list.
