Multiple conditional violin plots

Discover relationships between numeric variables and categorical target variable

Draw conditional violinplots. Select one to eight numeric columns at a time. Selecting columns more than eight generates no error but plots are displayed only for the first eight columns. Input is a Knime dataframe. Violinplots are subsetted (or grouped by) a categorical variable (also to be selected from dataset). It is advisable to shuffle the data before feeding here. For better results, normalize input data.

r packages required are ggplot2, grid and gridExtra.
