R（circlize）：如何删除自链接？

Question

这是一个示例代码：

df <- rbind(matrix(rep(sample(5),2),5,2),matrix(sample(10),5,2))

model_color <- unique(as.vector(df))
names(model_color) <- model_color

brand <- unique(as.vector(df))
names(brand) <- brand

chordDiagram(data.frame(df), order = names(brand), grid.col = model_color, directional = 0)
circos.clear()

如何 "mask" 自链接？我想删除它们，使 space 为空（右图）。

Answer 1

这似乎有效...

transparency <- ifelse(df[,1]==df[,2],1,0.5)
chordDiagram(data.frame(df), order = names(brand), 
         transparency=transparency,grid.col = model_color, directional = 0)
