2018-03-17 * Version 1.5.4 released 2014-02-20 * Version 1.5.3 released. 2013-12-07 * survival listed only in Enhances rather than Suggests, fixing package check NOTE. 2013-02-11 * Added arguments "tcol" and "mcol" to denstrip to change the colours of tick marks. 2012-04-02 * .filled.contour replaces .Internal call in densregion. The package therefore now depends on R 2.15 or later. * Default value of 1 added to "max" argument in denstrip.legend, fixing the problem revealed by R-devel. * Version 1.5.2 released 2011-07-25 * Fix for densregion with very small numbers of unique densities. Thanks to Daniel Chainey for the report. 2011-01-17 * Fix for error in NAMESPACE which caused CHECK fail. * Version 1.5.1 released 2010-05-18 * Version 1.5 released 2010-05-06 * Added "colmin" argument to all functions which accept "colmax", If set to "transparent", allows overlapping strips and regions to merge smoothly, on all devices which support transparency. Thanks to Anne Presanis for the suggestion. 2009-10-07 * Accept data frames as well as matrices in cistrip(), as long as all entries are numeric. 2009-09-24 * Version 1.4 released 2009-09-17 * x and y limits in lattice plots taken from current.panel.limits() instead of trellis.last.object(), so that it works when one axis shows factor levels. Example of use of denstrip with "bwplot" added to help(denstrip). Thanks to Kevin Wright for the suggestion. 2009-03-23 * Examples using "Surv" changed for compatibility with new survival package in upcoming R 2.9.0. * New argument "contour" to densregion.default to show contour lines of constant density value. * Version 1.3 released 2008-11-07 * cistrip now allows different "pch" for each element in a vector of strips. Similarly, the point sizes can be varied with a "cex" argument. 2008-11-03 * References updated to published version of the paper. * Version 1.2 released. 2008-09-09 * Code of the form seq(0, 1, length=n+2)[-c(1,n+2)] replaced by ppoints(n, a=0) 2008-08-28 * Panel functions for all strips implemented for use with lattice graphics. Thanks to Austin Frank for the suggestion. * Sectioned density plots can now point downwards or rightwards. * Border drawn around lightest box in sectioned density plot. * cex property added to denstrip.legend. * User-specified axis ticks supported in denstrip.legend. * default axis tick annotations in denstrip.legend now have 3 significant figures instead of 2 decimal places. 2008-08-21 * Version 1.1 released 2008-08-19 * Eliminated dependency on R.utils by re-implementing seqToIntervals function in sectioned.density(). Thanks to Tobias Verbeke for the suggestion. 2008-08-15 * alpha channel supported in all user-specified colors. 2008-08-15 * Version 1.0 released.
