genNthEvent: Generate event data using longitudinal data, and restrict output to time until the nth event.

Description

Generate event data using longitudinal data, and restrict output to time until the nth event.

Usage

genNthEvent(dtName, defEvent, nEvents = 1, perName = "period", id = "id")

Value

data.table that stops after "nEvents" are reached.

Arguments

dtName

name of existing data table

defEvent

data definition table (created with defDataAdd) that determines the event generating process.

nEvents

maximum number of events that will be generated (the nth event).

perName

variable name for period field. Defaults to "period"

id

string representing name of the id field in table specified by dtName

Examples

defD <- defData(
  varname = "effect", formula = 0, variance = 1,
  dist = "normal"
)
defE <- defDataAdd(
  varname = "died", formula = "-2.5 + 0.3*period + effect",
  dist = "binary", link = "logit"
)

d <- genData(1000, defD)
d <- addPeriods(d, 10)
dx <- genNthEvent(d, defEvent = defE, nEvents = 3)
