Added labels to hdrscatterplot (thanks to Fan Cheng)
Version 3.32018-12-21
More options for hdr.boxplot (thanks to Simon Carrignon)
More flexible hdr.den plots (thanks to Simon Carrignon)
Fixed colours in hdrscatterplot
Version 3.22018-01-29
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
Version 3.12013-10-19
Added dependency on mvtnorm to avoid problems with ks.
Version 3.02013-08-28
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.
Version 2.162012-03-30
Replaced .Internal() calls with new .filled.contour() function.
Version 2.152010-11-11
Added option to control limits of density estimate in hdr.boxplot.2d()
Version 2.142010-04-20
Updated references for hdrbw().
Version 2.132010-01-26
*Added color options to hdr.boxplot.2d().
Version 2.122009-10-13
*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.
Version 2.112009-09-18
Added hdrbw() from Matt Wand to compute better bandwidths for hdr(), hdr.den() and hdr.boxplot().
Fixed a few bugs in the help files.
Version 2.102009-08-19
Bug fix in hdr.boxplot.2d(). The show.points option was not working.
Version 2.092008-11-20
Bug fix: the a bandwidth in cde() when fw=TRUE and use.locfit=TRUE was twice as large as it should have been.
Version 2.082008-10-08
*Bug fix inhdr.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.
