Create seed

This function wraps the seed_engine to operate across all locations in the input signal.

Usage

plane_seed(input, cut_date = NULL)

Arguments

input

Input signal data used for seeding; must be an observed signal object

cut_date

Maximum date (inclusive) for which seeding should be performed; default is NULL and the entire input will be used for seeding

Value

A named list of length n, where multiple elements corresponding to seed characteristics and metadata for each of the n locations are nested in independent lists.

Examples

## read in example observed data and prep observed signal
hosp <- read.csv(system.file("extdata/observed/hdgov_hosp_weekly.csv", package = "rplanes"))
hosp$date <- as.Date(hosp$date, format = "%Y-%m-%d")
prepped_observed <- to_signal(hosp, outcome = "flu.admits", type = "observed", resolution = "weeks")

## prepare seed with no cut date
plane_seed(prepped_observed)

## prepare seed with cut date
plane_seed(prepped_observed, cut_date = "2022-10-29")
