gen.evl: Generate numeric categories of events.

In informR: Sequence Statistics for Relational Event Models

Description

Generate numeric categories of events in an idXevent list.

Usage

gen.evl(eventlist, null.events=NULL)

Arguments

eventlist	Either a two (2) or three (3) column matrix or data.frame. See Details.
null.events	A character vector of event values that should be treated as 0 in the eventlist. Default is NULL.

Details

For interval (or continuous) relational event models, eventlist must be a three column matrix where the first column indexes the events, the second column indexes the temporal information of when the event transpired, and the third column indexes an event history grouping factor (possibly, for instance, the name(s) of the actor(s)). For each unique value of the grouping factor, the corresponding events must be given in ascending temporal order. For ordinal (or discrete) relational event models, eventlist must be a two column matrix with the first column indexing the events and the second column indexing the event history grouping factor.

Value

A list containing:

eventlist	Vector of integers representing numeric codes for events. Has attr(,"char"), which represents the character representation of those values.
event.key	A key identifying the unique ids of each verbose event type.
null.events	if(!is.null(null.events)), a vector of null events.

Examples

rawevents<-sample(rep(c("ran","eat","stay","eat","ran","play"),100))
actors<-rep(c("Jim","Bill","Pete"),10)
eventlist<-cbind(rawevents,actors)
evls<-gen.evl(eventlist)
evls$eventlist$Bill
evls$event.key

#Compare with:
evls<-gen.evl(eventlist,null.events=c("ran","eat"))
evls$eventlist$Bill
evls$event.key
evls$null.events
