ggraph中的长格式和宽格式等价物

Question

我正在尝试制作类似于此的图表：

else if

我想指定library(tidyverse) library(ggraph) iris_g <- den_to_igraph(as.dendrogram(hclust(dist(iris[1:4])))) xy_expand <- function(xy, expand) xy * (1 + expand / 10) ord <- match(as.numeric(V(iris_g)$label), seq_len(nrow(iris))) V(iris_g)$Petal.Length <- iris$Petal.Length[ord] V(iris_g)$Petal.Width <- iris$Petal.Width[ord] V(iris_g)$Sepal.Length <- iris$Sepal.Length[ord] V(iris_g)$Sepal.Width <- iris$Sepal.Width[ord] V(iris_g)$Species <- iris$Species[ord] ggraph(iris_g, layout = "dendrogram", circular = TRUE) + geom_edge_diagonal() + geom_node_point(aes(filter = leaf, x = xy_expand(x, Sepal.Length), y = xy_expand(y, Sepal.Length)), color = "red") + geom_node_point(aes(filter = leaf, x = xy_expand(x, Sepal.Width), y = xy_expand(y, Sepal.Width)), color = "green") + geom_node_point(aes(filter = leaf, x = xy_expand(x, Petal.Length), y = xy_expand(y, Petal.Length)), color = "blue") + geom_node_point(aes(filter = leaf, x = xy_expand(x, Petal.Width), y = xy_expand(y, Petal.Width)), color = "yellow") ，以便着色很好地集成到图的其余部分，但我无法弄清楚aes(color = Trait)

中是否存在等效的长数据格式

我想在ggraph中做的事情相当于：

ggplot
