Conditional densityplots of multiple numeric columns

Discover relationship between numeric variables & discrete target variable
==========================================================================
Draw conditional densityplots. 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 dataset from a KNIME dataframe. It is advisable to shuffle the data before feeding here. r packages required are ggplot2, grid and gridExtra.
Density plots are subsetted (or grouped by) a discrete variable (also to be selected from dataset). For better results, normalize input data.
