Append positions

Source: R/DataPrep.R
appendPosition.Rd

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

Positions are centroids of areas. For oddly shaped (concave) areas, this can have unintended effects. The centroid may for instance lie outside the area.

Usage

appendPosition(
  table,
  areaPolygons,
  areaName,
  latColName,
  lonColName,
  StratumName = "StratumName"
)

StratumName

name of the column in 'areaPolygons' that identifies the area.

Value

'table' with the positions appended in the columns 'latColName' and 'lonColName'.
