Lexis.points

R Documentation

Plots ages and calendar years at transitions in Lexis diagram

Description

Plots observations in age-time diagram for each category of categorical covariate (using ggplot2)

Usage

Lexis.points(Bdata, transition, title, cov,group,legend.pos,pdf)

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
`group`	Covariate. Graphs for groups are in separate panels.
`legend.pos`	position of legend
`pdf`	If graph should be stored in pdf file: pdf=TRUE, else pdf=FALSE

Value

graph

Note

requires ggplot2

Examples

#  Example 1: ages at labour market entry, by sex
  data(GLHS)
  #y <- Parameters(GLHS)
  t <- "Date and age at labour market entry by sex and cohort"
  z <- Lexis.points (GLHS,"NJ",title=t,cov="sex",group="cohort",legend.pos="right",pdf=FALSE)

#  Example 2: ages at first birth among married women, by religious denomination
  data(NLOG98)
  y <- Parameters (NLOG98)
  t <- "Date and age at first birth (married women) by religion and cohort"
  z <- Lexis.points (NLOG98,"MK",title=t,cov="kerk",group="cohort",legend.pos="right",pdf=FALSE)
#  Example 3: ages at leaving home, by birth cohort (any destination)
  t <- "Date and age at leaving parental home by religion and education"
  z <- c(0.7,0.2)
  z <- Lexis.points (NLOG98,"H*",title=t,cov="kerk",group="educ",legend.pos=z,pdf=FALSE)
