Violin Plots in R

This package allows extensive customisation of violin plots.

Migration

This is a development branch of the vioplot 0.3 release. The package has been migrated to:

https://github.com/TomKellyGenetics/vioplot

Installation

To get the current released version from CRAN:

install.packages("vioplot")

To get the modified version from github:

# install.packages("devtools")
devtools::install_github("TomKellyGenetics/vioplotx")

Running

See the relevant vignette for more details:

• Customising colour and shape with scalar inputs or vectors applied separately to each violin.

https://rawgit.com/TomKellyGenetics/vioplotx/master/vignettes/violin_customisation.html

• Formula input enabled with S3 methods.

• Control of violin area for proportional widths

https://rawgit.com/TomKellyGenetics/vioplotx/master/vignettes/violin_area.html

• Control of the y-axis including disabling labels and log-scale

https://rawgit.com/TomKellyGenetics/vioplotx/master/vignettes/violin_ylog.html

• Split violins to directly compare paired data.

Functionality

vioplotx works in much the same manner as vioplot:

• vioplotx::vioplotx() generates a violin plot takes the same arguments as vioplotx::vioplotx() to plot a violin for each group of variables.

• vioplotx::vioplotx() also takes additional arguments to specify main, sub, xlab, and ylab as used in plot or title

• vioplotx::vioplotx() can take vectorised forms of colour variables col, border, and rectCol to modify the colours separately for each violin respectively. This also applies to a new variable lineCol to modify the colour of the boxplots.

• vioplotx::vioplotx.formula() is enabled to take formula and dataframe inputs as used for boxplot and stats operations.

• additional areaEqual, plotCentre and side options enables further customisation.
