Aggregate covariates
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"
)
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". |
Value
A data frame with the aggregated covariate.
