An example Analysis of R language correlation Matrix

This article introduces the relevant knowledge of "R language correlation matrix case analysis". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

R built-in function cor () can be used to calculate the correlation coefficient: cor (x, method = c ("pearson", "kendall", "spearman")), and the correlation coefficients of pearson, kendall and spearman can be calculated.

The cor function calculates the correlation coefficient between columns, and the proof C (iMagazine j) is the correlation coefficient between column I and column j.

For example, the following data:
