相关系数渐变圈图
简介
使用极坐标来展示多组的相关性,内圈为相关性,颜色表示相关性,越红表示相关性正向越大,越蓝表示相关性负向越大,内圈的数字表示相关性和显著性(*:小于0.05,**:小于0.01;***:小于0.001);外圈是分组弧线。
数据说明
输入为3列:第一列是基因名,第二列是相关性(有正有负),也可以是log2fc,甲基化Δβ值等,第三列是p值(或者FDR等,范围0-1,不能为0)。
输入为4列:第一列是基因名,第二列是相关性(有正有负),也可以是log2fc,甲基化Δβ等值等,第三列是p值(或者FDR等,范围0-1,不能为0),第四列是分类(例如不同的通路,需要内部排序,不能穿插)。请在excel里边排好序
