我有一个CSV文件，其中包含5个变量的p值的回归系数，我想在R中为这些变量绘制热图，并在热图中为每个变量添加p值。我得到了带有系数值的热图，但我不知道如何在每个单元的相同热图上添加p值。
以下是我用来创建热图的代码行：
heat_map = read.csv("data.csv",header=TRUE)
heat_map <- data.matrix(heat_map)
heatmap.2(heat_map, trace="none", margins=c(8,10), keysize=1, Rowv=NULL, Colv=NULL,
scale="none",col=greenred(75) ,cexRow=1.5,cexCol=1.5,cellnote = heat_map,
notecol = "white",density.info = "none",main = "main")
var1 Pv_var1 var2 Pv_var2 var3 Pv_var3 var4 Pv_var4 var5 Pv_var5
