"R" means the correlation coefficient, only in the range of-1 to +1. If the data closer to the +1, that they had a strong positive correlation. In contrast, if you are close to-1, to prove that they have a very strong negative correlation. There is also a number is equal to 0...

correlation coefficient, denoted by r, is a measure of the strength of the straight-line or linear relationship between two variables. The correlation coefficient takes on values ranging between +1 and -1. The following points are the accepted guidelines for interpreting the correlation coefficient:...

Noun1.coefficient of correlation- a statistic representing how closely two variables co-vary; it can vary from -1 (perfect negative correlation) through 0 (no correlation) to +1 (perfect positive correlation); "what is the correlation between those two variables?" ...
Different types of correlation coefficients are used to assess correlation based on the properties of the compared data. By far the most common is thePearson coefficient, known as “Pearson’s R,”which measures the strength and direction of a linear relationship between two variables. ...
