Retrieve Reasons for Not Achieving Good Status

Retrieves details of Reasons for Not Achieving Good (RNAG) status and Reasons For Failure (RFF) from EA Catchment Data Explorer site. Data can be retrieved by specifying waterbody id (WBID), Management Catchment (MC), Operational Catchment (OC) or River Basin District (RBD). Start year (startyr) and end year (endyr) allow specific timeranges to be downloaded. For Management Catchment (MC), Operational Catchment (OC) or River Basin District (RBD) level downloads, waterbody type can also be specified to allow extraction of specific waterbody types (River, Lake etc). Data are presented at the level of individual elements that are the reasons for not achieving good status.

Usage

get_rnag(ea_name = NULL, column = NULL, type = NULL)

Arguments

ea_name

A string representing the description (name for OC, MC or RBD level downloads or WBID for individual waterbodies) of the features to be extracted. For example to extract data for the whole of the Humber RBD, this would be "Humber"; also see examples. Must be an exact match to the values used in the EA database. Use the search_names function to search for specific values.

column

The column to be searched. Possible options are WBID (waterbody id), OC (Operational Catchment), MC (Management Catchment) and RBD (River Basin District)

type

Type of waterbody to be extracted. For Operational/Management catchment level or RBD level queries, the data can also be subset by waterbody type. Possible values are River, Lake, GroundWaterBody, TransitionalWater or CoastalWater.

Value

An object of class cde_df containing the details of the Reasons for Not Achieving Good Status for the specified combination of criteria. For details of the meaning of the the different columns returned, see https://docs.ropensci.org/cde/articles/cde-output-reference.html.
