stat_ellipse()中增加参数,按cluster画填充 ggplot(dat,mapping = aes(x=tSNE_1, y=tSNE_2, col=cluster))+ geom_point()+ stat_ellipse(aes(fill=cluster), geom = "polygon") 把填充的透明度改一改 ggplot(dat,mapping = aes(x=tSNE_1,
geom_ord_ellipse()函数参数中的fill好像只能填充一种颜色。默认无填充。 ggplot2自带的stat_ellipse() 同样0.8参数情况下会绘制不同大小的圈。 用法: p+stat_ellipse(aes(fill=group),geom="polygon",level=0.8,alpha=0.1,show.lengend=F)#或者p+stat_ellipse(aes(color=group),level=0.8,linetype=2,show....
使用stat_unique()移除重复值: stat_unique(mapping = NULL, data = NULL, geom = "point", position = "identity", ..., na.rm = FALSE, show.legend = NA, inherit.aes = TRUE) 1. 2. 3. 参数注释: geom:指定几何图层,默认值是point ...
