seqeconstraint: Setting time constraint

Description

Function used to set time constraint in several event sequences methods such as seqefsub(searching frequent subsequences).

Usage

seqeconstraint(maxGap = -1, windowSize = -1, 
  ageMin = -1, ageMax = -1, ageMaxEnd = -1)

Arguments

maxGap
The maximum time gap between to event
windowSize
The maximum window (subsequences time)
ageMin
Can be used to set a time period. If equal to -1 (default), it won't be considered.
ageMax
Can be used to set a time period. If equal to -1 (default), it won't be considered.
ageMaxEnd
Can be used to set a time period. If equal to -1 (default), it won't be considered.

Value

  • A constraint object containing one item per constraint type.

Details

maxGap, windowSize, ageMin, ageMax and ageMaxEnd. If so, two event should not be separated by more than maxGap and the whole subsequence should be included in a maximum time of windowSize. The other parameters specify the start and end age of the subsequence, it should start between ageMin and ageMax and finish before ageMaxEnd.
