This function provides some additional propoerties to the standard boxplot display. The basic old syntax of boxplot is retained, for compatibility.
The primary purpose is to allow for GROUPED boxplots, or subplots, of color coded boxplots on the same graph. This is useful for boxplot data comparrisons over multiple variables. It is also possible to overlay boxplots or to simply color different sets differently.
This routine allows for subgroup plotting of colorcoded boxplots (boxplotCsub) using the subfunction boxplotC (which allows for multiple colored box plots to be overlayed). In addition, standard line color and line width definition is available, as well as the filled option. This allows for color coding multiple box plots and overlaying. Download ZIP contains boxplotCsub with a revised boxplotC and boxutilC.
Reverse compatible with standard boxplot old syntax. While less obvious than the current syntax, looking at the examples should help clarify usage for those unfamiliar with boxplot.
Due to changes in boxplot in v.2011, the old BOXPLOT syntax help has been inclued, along with several examples.
BOXPLOTC is now obsolete, and superceded by this function.
