R: Import air quality data from European database

importEurope {openair} | R Documentation

## Import air quality data from European database

### Description

This function is a simplified version of the `saqgetr` package (see https://github.com/skgrange/saqgetr) for accessing European air quality data. The function only returns valid hourly data and is meant as a fast and convenient way of accessing the most common type of hourly air quality data. The function works in the same way as other `openair` functions that import air quality data that generally need a site code and year to be supplied.

### Usage

    importEurope(
      site = "debw118",
      year = 2018,
      tz = "UTC",
      meta = FALSE,
      to_narrow = FALSE
    )

### Arguments

`site` | The code of the site(s).
`year` | 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.
`tz` | Not used
`meta` | Should meta data be returned? If `TRUE` the site type, latitude and longitude are returned.
`to_narrow` | 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.

### Details

The function can however return key site meta data.

The `saqgetr` package is much more comprehensive and provides data at other time averages e.g. daily data.

### Value

A tibble of data.

### Examples

     # import data for Stuttgart Am Neckartor (S)
    ## Not run: stuttgart <- importEurope("debw118", year = 2010:2019, meta = TRUE)
