Generate a periodic growth timeseries simulation

periodicGrowthRate(
  name,
  dateAtTime0 = "2020-01-01",
  length = 365,
  period = 91,
  baseline = 0,
  smooth = TRUE,
  amplitude = 0.1,
  Gt.mean = 5,
  Gt.sd = 4
)

Arguments

name

- a meaningful name for this growth rate scenario
dateAtTime0

- the date at time zero
length

- how many days in the scenario
period

- the period of the periodic function
baseline

- a baseline growth rate around which to oscillate usually 0.
smooth

- smooth (sinusoidal) or triangular wave.
amplitude

- growth rate (or R_t) amplitude
Gt.mean

- mean of the generation time for conversion to R_t
Gt.sd

- sd of the generation time for conversion to R_t

Value

- a list containing name - the scenario name, ts - a tibble with the date, generated growth rate and R_t values, events - the time-points of the period, infectivityProfile - an infectivity_profile
