Monitor weather reports daily to remain prepared for high heat index levels. However, while R offers a simple way to create such matrixes through the cor function, it does not offer a plotting method for the matrixes created by that function. Correlation can have a value: 1 is a perfect positive correlation; 0 is no correlation (the values don't seem linked at all)-1 is a perfect negative correlation; The value shows how good the correlation is (not how steep the line is), and if it is positive or negative. Occasionally you will see a perceptual map that also maps the preferred needs of different market segments, based on the same attributes.
