2019-11-20sankeywheel包画桑基图

许多R包都可以画桑基图和轮状图，如 circlize, networkD3, and ggalluvial。
这些包都非常好，非常有用。问题来了，吃饱了撑的再弄一个同样的画图包。
作者说了，桑基图和轮状图有些关联，一个R包画两张图，岂不更美。于是乎就有了sankeywheel，除此之外，这个包使用“Highcharts”增加了交互性，另外这个包更简单易用。

1、先安装包

devtools::install_github('czxa/sankeywheel', build_vignettes = TRUE)

devtools::install_git("https://github.com/czxa/sankeywheel.git", build_vignettes = TRUE)

install.packages("sankeywheel")

2、基本使用

library(sankeywheel)
head(sankeydf)#用它内置的数据集
# A tibble: 6 x 3
  from   to       weight
  <chr>  <chr>     <dbl>
1 Brazil Portugal      5
2 Brazil France        1
3 Brazil Spain         1
4 Brazil England       1
5 Canada Portugal      1
6 Canada France        5

3、画轮状网络图

sankeywheel(from = sankeydf$from,
            to = sankeydf$to,
            weight = sankeydf$weight,
            type = "dependencywheel", 
            width = "100%")

4、画桑基图

sankeywheel(from = sankeydf$from,
            to = sankeydf$to,
            weight = sankeydf$weight,
            type = "sankey", 
            width = "100%")

4、更改主题参数

library(manipulateWidget)
combineWidgets(
  sankeywheel(from = sankeydf$from,
            to = sankeydf$to,
            weight = sankeydf$weight,
            type = "sankey", 
            width = "100%",
            theme = "sunset", 
            title = "SUNSET"),
  sankeywheel(from = sankeydf$from,
            to = sankeydf$to,
            weight = sankeydf$weight,
            type = "dependencywheel", 
            width = "100%", 
            theme = "sunset", 
            title = "SUNSET"),
  byrow = TRUE, ncol = 2, width = "100%", height = "300px"
)

            seriesName = "Random data: ",
            width = "100%",

            titleColor = "black",
            subtitle = "czxa.top",
            subtitleAlign = "center",
            subtitleSize = "14px",
            subtitleColor = "black")
