Lexis.lines: Draws Lexis diagram with lifelines for selected subjects

In Biograph: Explore Life Histories

Description

The function draws a Lexis diagram and draws lifelines for selected subjects (using ggplot2 package)

Usage

Lexis.lines(Bdata,Dlong, subjectsID, title)

Arguments

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.

Details

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 object.

Value

subjectsID	Subjects selected
p	The plot of the lifelines

Note

requires ggplot2

Examples

#  Example 1: Employment careers
  data(GLHS) 
  z<- Parameters (GLHS)
  GLHS.yr <- date_b(Bdata=GLHS,selectday=1,format.out="year")
  D <- Biograph.long (GLHS.yr)
  tit5 <- "Employment careers for a selection of subjects. GLHS"
  subjects <- c(1,78,120,208)
  z <- Lexis.lines (Bdata=GLHS.yr,Dlong=D$Depisode,subjectsID = subjects,title = tit5)

#  Example 2: Long data format need to be obtained
  z <- Lexislines.episodes (Bdata=GLHS.yr,subjectsID = subjects,title = tit5)  

#  Example 3: Living arrangements 
  data(NLOG98)
  z<- Parameters (NLOG98)
  NLOG98.yr <- date_b(Bdata=NLOG98,selectday=1,format.out="year")
  D <- Biograph.long (NLOG98.yr)
  tit5 <- "Living arrangements for a selection of subjects, NLOG98"
subjectsID <- c(8,96,980,1056,1496,2883)
  z <- Lexis.lines (NLOG98.yr,D$Depisode,subjectsID = subjectsID,title = tit5)
