[R] Splitting survivor episodes

[Daniel A. Powers]

To R-list --

Does anyone know of an R function that will create split-episode data from
single spell event/duration data according to user-defined time intervals?

Example: original data
 t     d  x
------------
 6     0  x1
 5     1  x2

Split using intervals [0,3) [3,infty) (or cutpoint at 3)

 start end    event
 _t0    _t     _d   _x  episode
   0     3      0   x1   1
   3     6      0   x1   2
   0     3      0   x2   1
   3     5      1   x2   2

Thanks,
Dan
