EEAaq_time_aggregate {EEAaq}

Time aggregation of an EEAaq_df class object.

Description

EEAaq_time_aggregate compute a time aggregation of an EEAaq_df or EEAaq_df_sfc class object, based on the specified frequency and the aggregation functions aggr_fun.

Usage

EEAaq_time_aggregate(
  data = NULL,
  frequency = "monthly",
  aggr_fun = c("mean", "min", "max")
)

Arguments

data

an EEAaq_df or EEAaq_df_sfc class object, which is the output of the EEAaq_get_data function.

frequency

vector containing the time frequency for which to aggregate the data object. Admissible values are 'yearly', 'monthly', 'weekly', 'daily' 'hourly'.

aggr_fun

character vector containing one or more agregation functions. Admissible values are 'mean', 'median', 'min', 'max', 'sd', 'var', 'quantile_pp' (where pp is a number in the range [0,1], representing the required percentile).

Value

A EEAaq_taggr_df or a EEAaq_taggr_df_sfc class object, which is a tibble containing the required time aggregation.

Examples

data <- EEAaq_get_data(zone_name = "Milano", NUTS_level = "LAU",
  pollutant = "PM10", from = 2023, to = 2023, ID = FALSE, verbose = TRUE)
EEAaq_time_aggregate(data = data, frequency = "monthly", aggr_fun = c("mean", "min", "max"))
EEAaq_time_aggregate(data = data, frequency = "yearly", aggr_fun = "mean")
