In MGousseff/r2spmf: Links R 2 the SPMF Library for frequent itemsets and sequences mining

Description

This function is not to be used directly, it is called by df2spmfBasket

Usage

ToTimedSequence(x, timeStep = timestep, timeUnit = timeUnit,
  timeFormat = timeFormat)

Arguments

x	a dataframe which must contains variable ID, itemset, eventNum and time
timeStep	if time is taken into account in the building of the sequence, this parameter allows to perform an integer division. For instance, if your time is in days but you wish to perform a time constrained sequence mining grouping relying on weeks, timeStep will be 7.
timeUnit	this parameter will be used in future versions
timeFormat	this parameter is inherited from the df2SPMFSequence function

Examples
