Conditional boxplots of multiple numeric columns

Discover relationships between numeric variables and a categorical target variable
Draw conditional boxplots. Select one to eight numeric columns at a time. Selecting columns more than eight generates no error but plots are displayed only for first eight columns. Input is a Knime dataframe.

Boxplots are subsetted (or grouped by) a discrete variable (also to be selected from dataset). For better results, normalize input data. It is advisable to shuffle the data before feeding here.

r packages required are ggplot2, grid and gridExtra.
