Description

Append area code

Usage

appendAreaCode(
  table,
  areaPolygons,
  latName,
  lonName,
  colName,
  StratumName = "StratumName",
  strict = T
)

Arguments

table	data.table to be annotated.
areaPolygons	sf data.frame
latName	name of WGS84 lat column in 'table'
lonName	name of WGS84 lon column in 'table
colName	name of column to be appended to 'table'
StratumName	name of column in 'areaPolygons' that identify the area name
strict	logical determining whether to run in strict mode. See details.

Details

Appends a column with an area code to a table, based on positions.

If polygons are overlapping, so that one point may be in several polygons, an arbitrary choice is made and a warning is issued.

By default this function is run in 'strict' mode, meaning that it will halt with an error if some positions are not in any of the provided polygons, or if some positions are missing (NA). Turning of strict-mode accepts both these cases and the area code will be NA for these positions.

Value

'table' with the area appended in the column 'colName'
