Multiple side-by-side scatter plots against one target

Discover relationships between multiple numeric columns and a numeric target column
Draw scatterplots, side-by-side, between continuous target and other continuous columns. Select one to eight 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 csv file reader. It is advisable to shuffle as also sample the data before feeding here. r packages required are ggplot2, grid and gridExtra.
Too many points will create clutter. For large dataset, you can also specify sample-size to plot. For better results, normalize input data. Scatter plots show how linear the relationships are.
