In timonelmer/dena: DENA - dynamic ego-centric network analysis

Adding rows with censored data points

Description

Creates extra rows for indicating left- or right-censored data.

Usage

censoringData(
  dat,
  nestVars,
  timeVar,
  eventVar = "event",
  catVar = NULL,
  TimeGap = 1,
  censoring = "right",
  verbose = T
)

Arguments

dat	data.frame containing the variables to be lagged
nestVars	name(s) of the columns indicating how the data is nested (e.g., ID variable). Currently up to two nestVars are possible.
timeVar	name of the column with the time variable.
eventVar	name of the column indicating if an event (value = 1) happened or not/censored (0)
catVar	name of the event (for coxph or frailty) or event-type (for multi-state) column where the indication of the censoring is stored.
censoring	character string "right" or "left" indicating if right- or left- censored data row should be added
timeGap	time to be added (for right-censoring) or removed (for left-censoring) form timeVar

Value

data.frame with extra rows for censored data.

Examples

 dat <- data.frame(ID = c(rep(1,10), rep(2,10)),
                  day = rep(c(rep(1,5), rep(2,5)),2),
                  event = 1,
                  a = runif(20, max = 10),
                  t = rlnorm(20,1,.4),
                  cat = sample(c("X","Y","Z"), 20, replace = T))
censoringData(dat, nestVars = c("ID"), timeVar = "t")
censoringData(dat, nestVars = c("ID","day"), timeVar = "t")
censoringData(dat, nestVars = c("ID"), timeVar = "t", censoring = "left",TimeGap = 1
