Description

Add cumulative count and summary stats for categories for exposure duration analysis

Usage

extend_exp_duration(
  outdata,
  category_section_label = NULL,
  duration_category_list = NULL,
  duration_category_labels = NULL
)

Value

A list of analysis raw datasets.

Arguments

outdata

An outdata object created by prepare_exp_duration().

category_section_label

A character value of section label. If NULL, the parameter label is used with "(cumulative)".

duration_category_list

A list of duration category ranges. Must be real numbers and may overlap or be mutually exclusive. A list should be in the form of list(c(low1, high1), c(low2, high2), ...). If NA is included in the range, it is treated as -Inf or Inf. The range is defined as low <= x < high for each.

duration_category_labels

A character vector of internal labels. Labels to be displayed for the duration_category_list values. Must be the same length as duration_category_list.

Examples

meta <- meta_sl_exposure_example()
outdata <- meta |> prepare_exp_duration()
outdata |>
  extend_exp_duration(
    duration_category_list = list(c(1, NA), c(7, NA), c(21, NA)),
    duration_category_labels = c(">=1 day", ">=7 days", ">=21 days")
  )
