  • extractFields() can draw shapes out of classified images with concave hulls besides the basic convex hulls (see figure)
  • ccLabel() allows change thresholds that are negative (extracts pixels below the threshold) and positive (extracts pixels above the threshold)
  • labelCheck() can automatically correct a character vector without a visual check, provided a set of potential cases
  • rankPlots() includes class diversity/richness as criteria to select sampling sites
