如何将对象转换为数据框类对象？

我正在尝试在 R 中创建桑基图，但我不断收到错误消息，其中一个参数需要是数据帧类对象。参见下文：

    library(d3Network)
    d3Sankey(Links = df2[ ,('value')], Nodes = df3[ , c('name')], Source = "source", 
    Target = "target")
Error in d3Sankey(Links = df2[, ("value")], Nodes = df3[, c("name")],  : 
Links must be a data frame class object.
    df2 <- as.data.frame(df2)
    d3Sankey(Links = df2[ ,('value')], Nodes = df3[ , c('name')], Source = "source", 
    Target = "target")
Error in d3Sankey(Links = df2[, ("value")], Nodes = df3[, c("name")],  : 
Links must be a data frame class object.
    typeof(df2)
  [1] "list"

有了这些信息，有谁知道如何将 df2 转换为数据框类对象？

原文

df2 df1

I'm trying to create a Sankey Plot in R, but I keep getting an error that one of the parameters needs to be a Data Frame Class Object. See below:

    library(d3Network)
    d3Sankey(Links = df2[ ,('value')], Nodes = df3[ , c('name')], Source = "source", 
    Target = "target")
Error in d3Sankey(Links = df2[, ("value")], Nodes = df3[, c("name")],  : 
Links must be a data frame class object.
    df2 <- as.data.frame(df2)
    d3Sankey(Links = df2[ ,('value')], Nodes = df3[ , c('name')], Source = "source", 
    Target = "target")
Error in d3Sankey(Links = df2[, ("value")], Nodes = df3[, c("name")],  : 
Links must be a data frame class object.
    typeof(df2)
  [1] "list"

With this information, does anyone know how to convert df2 to a data frame class object?

Links、Nodes 应该是 data.frames - Links data.frame 应该有三列 source、目标和值，具有单列名称的节点。在OP的代码中，两者都作为向量提供，因为在data.frame中，如果我们使用带有单个列名的,，它删除尺寸（drop = TRUE - 默认情况下）。为了保存输出，请指定file

library(d3Network)
d3Sankey(Links = df2[c('source', 'target', 'value')], 
   Nodes = df3[c('name')], Source = "source",   
     Target = "target", file = "sankeyfile.html")

The Links, Nodes should be data.frames - Links data.frame should have three columns source, target and value, Nodes with a single column name. In the OP's code, both are provided as vectors because in data.frame, if we use a , with a single column name, it drops the dimensions (drop = TRUE - by default). In order to save the output, specify file

library(d3Network)
d3Sankey(Links = df2[c('source', 'target', 'value')], 
   Nodes = df3[c('name')], Source = "source",   
     Target = "target", file = "sankeyfile.html")
