Determines for a given transition the number of transitions by age
Usage
TransitionAB(Bdata, transition,keep)
Arguments
Bdata
Biograph object
transition
Selected transition
keep
Logical variable indicating whether observations (subjects) with the selected transition missing should be kept (TRUE) or removed (FALSE). Default: keep=FALSE
Value
case
The transition
n
Number of subjects in the sample experiencing the selected transition (transition count).
id
Identification number of subjects that experienced the transition
pos
Position of the selected transition in the state sequence (path variable Bdata$path of the Biograph object). If transition = "*N" and N is the first state, then that state is skipped. If a subject experienced several of the selected transition, the first transition is considered.
date
For each subject experiencing the transition, date of transition
age
For each subject experiencing the transition, age at transition
year
For each subject experiencing the transition, year of transition (year is real variable, including fraction of year)
cohort
For each subject experiencing the transition, birth cohort

Examples
# Example 1: Transition NJ in GLHS data set
data (GLHS)
z <- TransitionAB (GLHS,"NJ",keep=TRUE)
# Example 2: Transition HM in NLOG98 data set
data (NLOG98)
z <- TransitionAB (NLOG98,"HM")
# Example 3: Transition 'Leaving parental home", irrespective of destination state
data (NLOG98)
z <- TransitionAB (NLOG98,"H*")
# Example 4: First marriage, irrespective of origin state
data (NLOG98)
z <- TransitionAB (NLOG98,"*M")
