Get SpatialLines of one Polygons feature

polygonRingHolesLines(
  Sr,
  density = 0.5,
  angle = 45,
  ID = 1,
  fillOddEven = FALSE
)

Arguments

Sr

An object of class Polygons

density

the density of shading lines, in lines per inch. The default value of NULL means that no shading lines are drawn. A zero value of density means no shading nor filling whereas negative values and NA suppress shading (and so allow color filling).

angle

the slope of shading lines, given as an angle in degrees (counter-clockwise).

ID

Number or string identifying the Polygon inside Polygons

fillOddEven

logical controlling the polygon shading mode: see below for details. Default FALSE.
