  - More options for hdr.boxplot (thanks to Simon Carrignon)
      - More flexible hdr.den plots (thanks to Simon Carrignon)
      - Fixed colours in hdrscatterplot

                  Changes in version 3.2 (2018-01-29)                   

  - Updated hdr.den() to demonstrate the calculation of hdr more clearly
    (thanks to Dennis Freuer for the suggestion)
      - Added hdrscatterplot() function
      - Roxygenized the package
      - Added pkgdown site

                  Changes in version 3.1 (2013-10-19)                   

  - Added dependency on mvtnorm to avoid problems with ks.

                  Changes in version 3.0 (2013-08-28)                   

  - Reduced dependency on KernSmooth and changed ::: calls to ::
      - New functions hdr.2d() and plot.hdr2d() to return and plot
        bivariate HDR information.
      - Rewritten hdr.boxplot.2d() function.

                  Changes in version 2.16 (2012-03-30)                  

  - Replaced .Internal() calls with new .filled.contour() function.

                  Changes in version 2.15 (2010-11-11)                  

  - Added option to control limits of density estimate in
    hdr.boxplot.2d()

                  Changes in version 2.14 (2010-04-20)                  

  - Updated references for hdrbw().

                  Changes in version 2.13 (2010-01-26)                  

  - Added color options to hdr.boxplot.2d().

                  Changes in version 2.12 (2009-10-13)                  

  - Modified hdr(), hdr.boxplot() and hdr.den() to allow a Box-Cox
    transformation to be used when computing the density. This allows
    the density estimate to be non-zero only on the positive real line.

                  Changes in version 2.11 (2009-09-18)                  

  - Added hdrbw() from Matt Wand to compute better bandwidths for hdr(),
    hdr.den() and hdr.boxplot().
      - Fixed a few bugs in the help files.

                  Changes in version 2.10 (2009-08-19)                  

  - Bug fix in hdr.boxplot.2d(). The show.points option was not working.

                  Changes in version 2.09 (2008-11-20)                  

  - Bug fix: the a bandwidth in cde() when fw=TRUE and use.locfit=TRUE
    was twice as large as it should have been.

                  Changes in version 2.08 (2008-10-08)                  

  - Bug fix in hdr.boxplot.2d(). It would sometimes plot outliers on a
    separate plot.
      - New argument to hdr.boxplot.2d() to allow the density to be
        estimated using the kde() function from the ks package.
