Lexislines.episodes: Draws Lexis diagram with lifelines for selected subjects
In Biograph: Explore Life Histories

Description Usage Arguments Details Value Note Author(s) References See Also Examples

The function draws a Lexis diagram, using the Lexis object defined in the Epi package, and draws lifelines for selected subjects.

1	Lexislines.episodes(Bdata,Dlong, subjectsID, title)

`Bdata`	Biograph object
`Dlong`	Input data in long format
`subjectsID`	Lifelines are drawn for subjects, identified by ID, included in the vector subjectsID.
`title`	Title of the Lexis diagram.

The function produces a Lexis object and plots the object for selected subjects. Transitions are marked on the lifelines. It requires data in long format. If the long format is not available, the function calls the function Biograph.long to produce the required format.

`Lcoh11`	Lexis object that includes all subjects
`Lcohh12`	Lexis object that includes selected subjects
`sub`	vector of IDs of subjects selected for the lifelines in the Lexis diagram
`k`	Number of subjects selected

requires Epi
