This function draws a correlation matrix of the radiomic dataset by corrplot
or pheatmap
.
Correlation matrix can be visualized by clustered correlation plot or heatmap.

rdr |
A RadAR object (class |
view_as |
(character) How to visualize correlation matrix? It can be "corrplot" or "heatmap". |
method_correlation |
(character) Which method use to calculate correlation. It can be one of the following: "pearson", "kendall", "spearman". |
method_hcl |
(character) Which method use for clustering matrix columns and rows. Available methods are "ward.D", "ward.D2", "single", "complete","average" , "mcquitty","median", "centroid". |
