dbscan_1.0-0

New Features

• The package has now a vignette.
• Jarvis-Patrick clustering is now available as jpclust().
• Improved interface for dbscan() and optics(): ... is now passed on to frNN.
• OPTICS clustering extraction methods are now called extractDBSCAN and
  extractXi.
• hullplot uses now filled polygons as the default.
• hullplot now used PCA if the data has more than 2 dimensions.
• kNN and frNN are now objects with a print function.
• dbscan now also accepts a frNN object as input.

dbscan_0.9-8

Changes in version 0.9-8 (2016-08-05)

• OPTICS: added a predecessor correction step that is used by
  the ELKI implementation (Matt Piekenbrock).
• Added hullplot to plot a scatter plot with added convex cluster hulls.
• Fixed a memory problem in frNN (reported by Yilei He).

dbscan_0.9-7

Changes in version 0.9-7 (2016-04-14)

• OPTICSXi is now implemented (thanks to Matt Piekenbrock).
• DBSCAN now also accepts MinPts (with a capital M) to be
  compatible with the fpc version.
• DBSCAN objects are now also of class db scan_fast to avoid clashes with fpc.
• DBSCAN and OPTICS have now predict functions.
• Added test for unhandled NAs.
• Fixed LOF for more than k duplicate points (reported by Samneet Singh).

dbscan_0.9-6

• OPTICS: fixed second bug reported by Di Pang
• all methods now also accept dist objects and have a search method "dist" which precomputes distances.

CRAN Release 0.9-5

• OPTICS: fixed bug with first observation reported by Di Pang
• OPTICS: clusterings can now be extracted using optics_cut

CRAN Release 0.9-4

• added tests (testthat).
• input data is now checked if it can safely be coerced into a
  numeric matrix (storage.mode double).
• fixed self matches in kNN and frNN (now returns the first NN correctly).
