以下代码根据层次聚类(使用
现在我想要更改两件事情:
hclust()
和 cutree()
)创建了一个区域地图(Choropleth map):library(plotly)
library(cluster)
hc <- hclust(dist(df), method = "complete")
df$member <- cutree(hc, 5)
cluster.means = (as.data.frame(aggregate(df[,-1], list(cluster= df$member), mean)))[,-4]
g = list(
scope = 'africa',
showframe = T,
showland = T,
landcolor = toRGB("white")
)
plot_ly(df, z = member, type = 'choropleth', locations = Country,
locationmode = 'country names', text = Country, hoverinfo = "text") %>%
layout(geo = g, title = "Energy markets in Africa")
现在我想要更改两件事情:
- 永久显示国家名称,即不仅在RStudio中悬停在交互式图表上时才显示。我尝试应用这篇文章的答案到我的代码中,但没有成功。
- 非连续比例尺。理想情况下,我希望完全没有比例尺,但是有5个盒子,每个盒子对应一个簇,具有以下三个特征:
(1) 盒子的颜色应该与其在区域分布图中的颜色相对应
(2) 每个盒子应包含分配给它的国家数量,即相应的簇
(3) 每个盒子应包含两个变量(X1,X2)的相应簇均值,这些变量包含在
cluster.means
中
我已经附上了一个这样的示例图,展示了我所想要的内容(它不必完全相同,只需传达思想即可)。
任何帮助、建议、提示都会受到高度赞赏!

比上面小0.1。最后我会像这样将它们全部连接起来box = list(box1,box2,box3,box4,box5)
并将box
分配给annotations
。但不幸的是,方框之间的距离不总是相同的...为什么? - Jonathan Rheinyanchor = "top"
即可。我已经编辑了答案。 - dww
