did you look at the survSplit() function in the survival library? you may
have to recode your date variable to a zero point, i.e. Jan 1 1900 = 0, and
measure your time like that. The survSplit function will split your
survival duration into specified cut points. I hope this helps

which is which (although you don't seem to need that).
Then, separately, you read your

But I am not sure if the reshape function can create new rows based on
the meeting variable. For the second act there are three meetings, i.e.
one meeting between discussion and agreement, and this should be entered
as a separate row.

they need to be split apart into separate cells)?
