Description

Aggregates a data frame containing disease cases in space and/or time.

aggregate_cases(
  data = NULL,
  cases = NULL,
  pop = NULL,
  time = NULL,
  area = NULL,
  pt = 1e+05,
  aggregate_space = NULL,
  aggregate_time = NULL
)

Arguments

• data: Data frame containing equally spaced (daily, weekly, monthly) incident cases for one or multiple areas.
• cases: Name of the variable that identifies the cases.
• pop: Name of the variable that identifies the population.
• time: Name of the variable that identifies the temporal dimension. The values must be in date format (“yyyy-mm-dd”) representing the day of observation for daily data, the first day of the week for weekly, or the first day of the month for monthly observations.
• area: Name of variable that identifies the different locations (e.g., areal units) for which a time series is available.
• pt: Scale of the person-time (default 100,000) for incidence rates.
• aggregate_space: Name of variable used to define spatial aggregation groups.
• aggregate_time: Temporal scale used to perform temporal aggregation. Options are: “week” (ISO 8601), “month”, “year”.

Returns

A data frame with the aggregated cases.
