Our solver is in R and we present the QP/QPY code, not to impress but to remind the developer to add more features to make the solver more useful, robust, fast and reliable.

Currently the box|violin|vio plot will only plot one of these types for each list.
The vioplot cannot be drawn for a dataframe and does not accept a main and a sub title.See previous posting on these topics.
Sep. 10: Vioplot can now process dataframes, by rewriting the code to draw the columns. If D is a dataframe with 3 columns for example, the code to draw a vioplot for this set is is vioplot(D[[1]], D[[2]], D[[3]]).
We will remove some of the limitation in a future version.
