R: Plot event dates and ages in Lexis diagram

Lexispoints

R Documentation

Plot event dates and ages in Lexis diagram

Description

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

Note

requires Epi

Author(s)

Frans Willekens. The Epi package used to plot the Lexis diagram was developed by Carstensen.

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")
