Changes in version 1.1.1                        

    o   Updated CITATION.

                 Changes in version 1.1.0 (2017-04-21)                  

    o   Major fucntional update. Sinaplot now works with data frames, lists,
	numeric vectors and formulas, similar to boxplot and beeswarm.

    o   Method "density" (default) no longer bins the y-axis on based on the supplied
	"bins" parameter. Instead the inferred bins from function "density()" are
	used.

    o   A random seed is added as an optional argument and can be used to control the
	random sample jittering and allow for plot reproducibility.

    o   NA's are automatically removed. A warning is thrown if NA values are present
	in the data informing about the number of cases removed.

    o   "labels" parameter controls the x-axis labels. Label rotation is removed. It
	is up to the user to control the label appearance.

    o   sinaplot returns an invisible object regardless of "plot" parameter.
	"bin_count" column is removed from the output.

    o   "color" is renamed to "col" to maintain consistency with 'graphics'
	functions.

    o   "col" and "pch" can be used and recycled if necessary to control the color and
	the shape of the points respectively.

    o   sinaplot can be added on top of other plots (i.e. boxplot) by using the 'add'
	parameter.

                 Changes in version 1.0.0 (2016-10-11)                  

    o   Major graphic update. SinaPlot now uses "base" graphics instead of ggplot2.
	geom_sina() is now part of ggforce (https://github.com/thomasp85/ggforce),
	an extention of ggplot2, and can be used to produce sinaplots with ggplot2.

    o   Major functional update. Several parameters have been added, renamed, replaced
	or removed.
	Read below for details.
	Added:

    o   "maxwidth" confines the spread of the samples along the x-axis. 0 is
	equivalent to no spread, 1 allows for maximum spread.

    o   Any argument can be passed to plot(), e.g. "cex" = 0.8, "pch" = 20, etc.
	Renamed:

    o   Method "neighbourhood" is renamed to "counts".

    o   "neighbLimit" is renamed to "bin_limit".

    o   "groupwiseScale" is renamed to "scale".
	Replaced:

    o   "yFraction" is replaced with "bins". Instead of specifying the fraction of
	the data range for each bin, now you provide the number of bins.
	Removed:

    o   "xSpread".

    o   "labels" .

    o   "main", "bw", "shape" and "size".

    o   If "plot == FALSE" the function returns a data frame with columns:
	x: discrete x-coordinates, split by group
	y: input values
	group: input groups
	bin_count: number of samples per bin per group
	scaled: final x-coordinates, adjusted by the sinaplot method

                        Changes in version 0.1.6                        

    o   Fixed a bug where having samples values overlapping the outermost y-bin
	boundaries produced an error (thanks to John Hoch).

                 Changes in version 0.1.5 (2016-05-18)                  

    o   Fixed a bug that was plotting the first and last classes beyond the figure
	margins.

                        Changes in version 0.1.4                        

    o   Fixed a bug where the data were reordered after calculating the new x-axis
	coordinates. This was creating problems when a user wanted to plot the samples
	with custom colors using sinaplot() + geom_point(col = mycol).

                 Changes in version 0.1.3 (2015-11-21)                  

    o   "groups" are treated as factors and they are plotted in the order that their
	levels appear (alphabetically by default) providing a similar output format with
	default ggplot2 plots.

                 Changes in version 0.1.2 (2015-10-03)                  

    o   NEWS file added.

    o   Changes in vignette compiling. knitr is added as the vignette builder in the
	DESCRIPTION FILE.

    o   Author details edited.

    o   Removed redundant "inst/temp.R" file.
