#' Population Time Plot Data
#'
#' Create a data frame for population time plots to give a visual representation
#' of incidence density
#'
#' @param data a \code{data.frame} or \code{data.table} containing the source
#' dataset.
#' @param time a character string giving the name of the time variable. See
#' Details.
#' @param event a character string giving the name of the event variable
#' contained in \code{data}. See Details. If \code{event} is a numeric
#' variable, then 0 needs to represent a censored observation, 1 needs to be
#' the event of interest. Integers 2, 3, ... and so on are treated as
#' competing events. If event is a \code{factor} or \code{character} and
#' \code{censored.indicator} is not specified, this function will assume the
#' reference level is the censored indicator
#' @param censored.indicator a character string of length 1 indicating which
#' value in \code{event} is the censored. This function will use
#' \code{\link[stats]{relevel}} to set \code{censored.indicator} as the
#' reference level. This argument is ignored if the \code{event} variable is a
#' numeric
#' @param exposure a character string of length 1 giving the name of the
#' exposure variable which must be contained in \code{data}. Default is
#' \code{NULL}. This is used to produced exposure stratified plots. If an
#' \code{exposure} is specified, \code{popTime} returns an `exposure`
#' attribute which contains the name of the exposure variable in the dataset.
#' The plot method for objects of class `popTime` will use this exposure
#' attribute to create exposure stratified population time plots.
#' @param percentile_number Default=0.5. Give a value between 0-1. if the
#' percentile number of available subjects at any given point is less than 10,
#' then sample regardless of case status. Depending on distribution of
#' survival times and events event points may not be evenly distributed with
#' default value.
#'
#'
#' @details It is assumed that \code{data} contains the two columns
#' corresponding to the supplied time and event variables. If either the
#' \code{time} or \code{event} argument is missing, the function looks for
#' columns that contain the words \code{"time"}, \code{"event"}, or
#' \code{"status"} in them (case insensitive). The function first looks for
#' the time variable, then it looks for the event variable. This order of
#' operation is important if for example the time variable is named
#' \code{"event time"} and the event variable is named \code{"event
#' indicator"}. This function will first (automatically) find the time
#' variable and remove this as a possibility from subsequent searches of the
#' event variable. The following regular expressions are used for the time and
#' event variables: \describe{ \item{time}{\code{"[\\s\\W_]+time|^time\\b"}}
#' \item{event}{\code{"[\\s\\W_]+event|^event\\b|[\\s\\W_]+status|^status\\b"}}
#' } This allows for \code{"time"} to be preceded or followed by one or more
#' white space characters, one or more non-word characters or one or more
#' underscores. For example, the following column names would be recognized by
#' the function as the \code{"time"} variable: \code{"time of death",
#' "death_time", "Time", "time", "diagnosis_time", "time.diag", "diag__time"}.
#' But the following will not be recognized: \code{"diagtime","eventtime",
#' "Timediag"}
#' @return An object of class \code{popTime} (or \code{popTimeExposure} if
#' exposure is specified), \code{data.table} and \code{data.frame} in this
#' order! The output of this function is to be used with the plot method for
#' objects of class \code{popTime} or of class \code{popTimeExposure}, which
#' will produce population time plots. This dataset augments the original data
#' with the following columns: \describe{\item{original.time}{value of the
#' time variable in the original dataset - the one specified by the
#' \code{time} user argument to this function}\item{original.event}{value of
#' the event variable in the original dataset - the one specified by the
#' \code{event} user argument to this function}\item{time}{renames the user
#' specified time column to time}\item{event}{renames the user specified event
#' argument to event}}
