有没有办法从factoextra包的fviz_cluster
函数中删除点(绘制factominer的包)。
正如你所看到的,这点有点乱,我想只保留聚类中心和椭圆体。
fviz_cluster(HCPC9CL, repel = FALSE, geom = "point", show.clust.cent = TRUE, ellipse.type = "norm", palette = trololo, ggtheme = theme_minimal(),
main = "Factor map")
答案 0 :(得分:2)
也许最简单的解决方案是设置alpha = 0
。
以下是一个例子:
set.seed(123)
data(iris)
iris.scaled <- scale(iris[, -5])
km.res <- kmeans(iris.scaled, 3, nstart = 10)
fviz_cluster(km.res, iris[, -5],
repel = FALSE,
geom = "point",
show.clust.cent = TRUE,
ellipse.type = "norm",
ggtheme = theme_minimal(),
main = "Factor map",
alpha = 0)
但是我建议不要删除这些点,而是要使它们透明,并且只使用颜色来区分它们:
fviz_cluster(km.res, iris[, -5],
repel = FALSE,
geom = "point",
show.clust.cent = TRUE,
ellipse.type = "norm",
ggtheme = theme_minimal(),
main = "Factor map",
alpha = 0.2,
shape = 19)
