带p值显著性标记的相关系数图
简介
根据两个输入的矩阵,计算第一个矩阵的列和第二个矩阵的列的相关系数和p值。图上显示相关系数,并以*或其他指定符号标注显著性。*越多,p越显著。调用corrplot
数据说明
输入数据包括两个矩阵。例如第一个矩阵表示基因的表达水平,第二个矩阵表示代谢物的信号。行表示样品,列表示特征。计算的是【第一个矩阵的列】 vs 【第二个矩阵的列】的相关系数。行数必需一样,列数可以一样,也可以不一样。

论文写作
Spearman correlation analysis for association analysis between gene expression and metabolites intensities. The color intensity (red and blue) and size of the circle indicate the strength of the correlation depicted as r-value. Asterisks on each circle indicate the P-value; ***≤ 0.001, **≤ 0.01 and *≤ 0.05. The analysis was performed using the corrplot package in R (v4.1).
