In Biograph: Explore Life Histories

Plots observations in age-time diagram for each category of categorical covariate (using the Lexis function of the Epi package)

Usage

Lexispoints(Bdata, transition, title, cov,legend)

Arguments

Bdata	Biograph object
transition	The transition selected, e.g. "NJ" in GLHS data
title	Title of Lexis diagram
cov	Covariate. Observations are plotted for each category of this covariate. If observations should be plotted for the total sample population, cov = NA
legend	legend

Value

Lcoh	Lexis object created to plot the observations

Examples

#  Example 1: ages at labour market entry, by sex
  library (Epi)
  data(GLHS)
  #y <- Parameters(GLHS)
  t <- "Calendar time and age at labour market entry"
  z <- Lexispoints (Bdata=GLHS,transition="NJ",title=t,cov="sex",legend="topleft")

#  Example 2: ages at first birth among married women, by religious denomination
  data(NLOG98)
  y <- Parameters (NLOG98)
  t <- "Calendar time and age at first birth (married women)"
  z <- Lexispoints (NLOG98,"MK",t,"kerk")
#  Example 3: ages at leaving home, by birth cohort (any destination)
  t <- "Calendar time and age at leaving parental home"
  z <- Lexispoints (NLOG98,"H*",t,"cohort","topleft")
