Multiple conditional density plots

Discover relationships between numeric variables and a categorical target variable

Conditional density plots are drawn. 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.
Density plots are subsetted (or grouped by) a string variable (also to be selected from the dataset). For better results, first normalize input data. It is also advisable to shuffle the data before feeding here.

R packages required are ggplot2, grid and gridExtra.
