Question

我的代码必须非常接近，但似乎有些小事情已经关闭。

library(treemap)

mydata = read.csv("C:\\Users\\rschuell\\Desktop\\top_10.csv")

products <- unique(mydata$product, incomparables = FALSE)

treemap(mydata, #Your data frame object
        index=products,  #A list of your categorical variables
        vSize = reportable_amount,  #This is your quantitative variable
        type="index", #Type sets the organization and color scheme of your treemap
        palette = "Reds",  #Select your color palette from the RColorBrewer presets or make your own.
        title="TreeMap of Products and Amounts", #Customize your title
        fontsize.title = 14 #Change the font size of the title
        )

我收到此错误消息：

Error in treemap(mydata, index = products, vSize = reportable_amount,  : 
  <index> contains invalid column names

我的数据集看起来像这样。

我有一个日期，产品重复几次，共有326种不同的记录。

我从下面的链接中得到了这个想法，我认为这非常有帮助。

Answer 1

我基本上使用以下代码。

library(treemap)
mydata = read.csv("C:\\Users\\rschuell\\Desktop\\all_pids.csv")

treemap(mydata, #Your data frame object
        index= "PID",  #A list of your categorical variables
        vSize = "Mar",  #This is your quantitative variable
    type="index",        
    palette = "Reds",  #Select your color palette from the RColorBrewer presets or make your own.
        title="TreeMap of Products and Amounts", #Customize your title
        fontsize.title = 14 #Change the font size of the title
        )

只有在我将负值更改为正数后才能工作。我不知道为什么所有的数据点都需要是积极的。我要调查一下。无论如何，这是一个非常好的工具，可以保存在一个工具箱中。

有趣的是，treemap在提供给索引的列名称中不接受下划线（_），因此，请对所有带有下划线的列进行重命名。

尝试创建树图，但获取有关无效列名称的消息
