Creates a correlation report that shows how much columns of a numeric matrix correlate with each other. Several methods for computing correlation coefficients are supported. The report contains a heat map that visualizes correlation coefficieents and a table that shows them in numeric form.

---|---|---|---|
method | string | "pearson" | Method for computing correlation. One of "pearson", "kendall" or "spearman". |
rotateLabels | boolean | true | If true, rotate column labels vertically in the correlation coefficient matrix so that they take less space on the x axis. Note: in the heat map, column labels are always rotated. |
showTable | boolean | true | Includes correlation matrix as a table into the report. |
