get_inboveg_classification: Query classification information from INBOVEG

In inbo/inbodb: Connect to and Retrieve Data from Databases on the INBO Server

Query classification information from INBOVEG

Description

This function queries the INBOVEG database for information on the field classification (N2000 or local vegetation type, e.g. BWK-code) of the relevé (recording) for one or more survey(s) by the name of the survey. See the examples for how to get information for all surveys.

Usage

get_inboveg_classification(
  connection,
  survey_name,
  classif,
  multiple = FALSE,
  collect = FALSE
)

Arguments

connection	dbconnection with the database 'Cydonia' on the inbo-sql07-prd server
survey_name	A character string or a character vector giving the name or names of the survey(s) for which you want to extract Classification information. If missing, all surveys are returned.
classif	A character vector giving the Classification code of the vegetation type for which you want to extract information. If missing, all classifications are returned.
multiple	If TRUE, survey_name can take a character vector with multiple survey names that must match exactly. If FALSE (the default), survey_name must be a single character string (one survey name) that can include wildcards to allow partial matches
collect	If FALSE (the default), a remote tbl object is returned. This is like a reference to the result of the query but the full result of the query is not brought into memory. If TRUE the full result of the query is collected (fetched) from the database and brought into memory of the working environment.

Value

A remote tbl object (collect = FALSE) or a tibble dataframe (collect = TRUE) with variables Id, SurveyName, Classification-code, vegetation type / BWK or N2000-list, LocalClassification, Description of the habitat type, Cover-code, Cover in percentage.
