Get or add stratum names from a SpatialPolygonsDataFrame

getStratumNames(
  stratumPolygon,
  StratumNameLabel = c("StratumName", "polygonName"),
  check.unique = TRUE,
  accept.wrong.name.if.only.one = FALSE
)

addStratumNames(
  stratumPolygon,
  StratumNameLabel = c("StratumName", "polygonName"),
  check.unique = TRUE,
  accept.wrong.name.if.only.one = FALSE
)

Arguments

stratumPolygon: A StratumPolygon.
StratumNameLabel: The name of the attribute representing the stratum names in the GeoJSON file or shapefile. When reading WKT or txt files the StratumNameLabel is ignored, as those formats does not support column names.
check.unique: Logical: If TRUE, an error is given if stratum names are not unique.
accept.wrong.name.if.only.one: Logical: If TRUE, interpret stratum names if only one column in the StratumPolygon.
