A matrix of scatterplots can be produced using pairs. Pairs function
takes various parameters like formula, data, subset, labels, etc.
The two key parameters required to
build a scatterplot matrix are –
formula- A formula basically like
~a+b+c . Each term gives a separate variable in the pairs plots where the terms
should be numerical vectors. It basically represents the series of variables
used in pairs.
data- It basically represents the
dataset from which the variables have to be taken for building a scatterplot.
