二、去掉刻度
chordDiagram(data,annotationTrack=c("name","grid",NULL))
三、调整顺序
chordDiagram(data,annotationTrack=c("name","grid",NULL),order=c("广州","深圳","佛山","中山","珠海","东莞"))
#使用order参数调整顺序，默认3点钟顺时针方向
四、调整外围sector颜色和透明度
> col<-c(广州="red",深圳="blue",佛山="darkcyan",中山="yellow",珠海="coral",东莞="bisque")
> chordDiagram(data,annotationTrack=c("name","grid",NULL),order=c("广州","深圳","佛山","中山","珠海","东莞"),grid.col=col,transparency=0.7)
