我正在尝试使用以下数据框和代码创建一个sankey图:
UKvisits <- data.frame(origin=as.character(c(
"France", "Germany", "USA",
"Irish Republic", "Netherlands",
"Spain", "Italy", "Poland",
"Belgium", "Australia",
"Other countries", rep("UK", 5))),
visit=as.character(c(
rep("UK", 11), "Scotland",
"Wales", "Northern Ireland",
"England", "London")),
weights=c(
c(12,10,9,8,6,6,5,4,4,3,33)/100*31.8,
c(2.2,0.9,0.4,12.8,15.5)))
Highcharter专栏:
hchart(UKvisits, "sankey", hcaes(from = origin, to = visit, weight = weights))
此示例已从此处复制:https://github.com/jbkunst/highcharter/blob/master/dev/highcharts-v6.R
出于某种原因,每当我运行时,绘图屏幕仍为白色,并且没有任何正在绘制的内容。
我在R Studio版本1.1.423(R版本:4.3)
上尝试此操作有人知道为什么会这样吗?
答案 0 :(得分:1)
我有同样的问题。首先,我收到了JavaScript控制台错误:
a is undefined
我没有在ui.R中使用正确的函数highchartOutput(),所以我在javascript控制台中找到了它:
Highcharts Error #17 The requested series type does not exist...
我发现this post,并有一条评论建议通过以下方式安装highcharter的开发版本:
devtools::install_github("jbkunst/highcharter")
然后使用该帖子中的简单代码为我解决了这个问题:
highchart() %>%
hc_chart(type = 'sankey') %>%
hc_add_series(
data = list(
list(from = 'AT', to = 'DE', weight = 10),
list(from = 'DE', to = 'CH', weight = 5),
list(from = 'DE', to = 'FI', weight = 5))
)
我能够从那里开始工作。似乎要制作Sankey图表,必须使用开发版本。
