Import data from locally managed AQ networks in England.
importLocal(
site = "ad1",
year = 2018,
data_type = "hourly",
pollutant = "all",
meta = FALSE,
to_narrow = FALSE,
progress = TRUE
)Site code of the site to import e.g. “ad1” is Adur,
Shoreham-by-Sea. Several sites can be imported with site = c("ad1",
"ci1") --- to import Adur and A27 Chichester Bypass, for example.
Year or years to import. To import a sequence of years from 1990
to 2000 use year = 1990:2000. To import several specific years use
year = c(1990, 1995, 2000) for example.
The data type averaging period. These include:
"hourly" Default is to return hourly data.
"daily" Daily average data.
"monthly" Monthly average data with data capture information for the whole network.
"annual" Annual average data with data capture information for the whole network.
"15_min" To import 15-minute average SO2 concentrations.
"8_hour" To import 8-hour rolling mean concentrations for O3 and CO.
"24_hour" To import 24-hour rolling mean concentrations for particulates.
"daily_max_8" To import maximum daily rolling 8-hour maximum for O3 and CO.
"daqi" To import Daily Air Quality Index (DAQI). See here for more details of how the index is defined.
Pollutants to import. If omitted will import all pollutants
from a site. To import only NOx and NO2 for example use pollutant =
c("nox", "no2").
Should meta data be returned? If TRUE the site type,
latitude and longitude are returned.
By default the returned data has a column for each
pollutant/variable. When to_narrow = TRUE the data are stacked into
a narrow format with a column identifying the pollutant name.
Show a progress bar when many sites/years are being imported?
Defaults to TRUE.
