Description

Aggregates a data frame containing a covariate of interest in space and/or time.

Usage

aggregate_cov(
  data = NULL,
  var = NULL,
  time = NULL,
  area = NULL,
  aggregate_space = NULL,
  aggregate_time = NULL,
  aggregate_space_fun = "mean",
  aggregate_time_fun = "mean"
)

Value

A data frame with the aggregated covariate.

Arguments

data

Data frame containing equally spaced (daily, weekly, monthly) incident cases for one or multiple areas.

var

Name of the variable that identifies the covariate.

time

Name of the variable that identifies the temporal dimension. The values must be in date format ("yyyy-mm-dd") representing the date 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 (i.e., areal units) for which a time series is available.

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".

aggregate_space_fun

Character indicating the function to be used in the aggregation over space, default is "mean".

aggregate_time_fun

Character indicating the function to be used in the aggregation over time, default is "mean".
