如何從數據框創建組合箱線圖？

Question

我想做一些令人難以置信的簡單：我想創建一個一個 boxplot爲一個完整的數據框。然而，搜索「組合盒子」和相關術語並沒有提出任何建議。如果我忽略了一個明顯的方式，請告訴我。

，我有以下數據：

我想在一個箱線圖所有數據彙總，然而，當我嘗試繪圖的箱線圖（即boxplot(theData)）R自動使基於列名小組。我也嘗試把完整的數據框放在一個向量中，但是，因爲我的（完整）數據集也包含NA值，所以我沒有成功。到目前爲止，我有以下幾個功能，儘量使數據幀的載體中，使得這可以在一個箱線圖繪製：

for(i in 1:ncol(allTheData)) { 
     tmpData <- allTheData[,i] 
     for(j in 1:length(tmpData)){ 
      if(!is.na(j)){ 
       tmpVector <- c(tmpVector, j) 
      } 
     } 
    } 

不過，我覺得我這個過於複雜的問題，我懷疑如果這樣的環路的建設將有利於R.

這樣的表現，我怎樣才能使其中包括一個箱圖的一個完整數據幀的箱線圖？那麼，我沒有得到由X20.7到X35.7組成的boxplot，但給出了一個「Overall」boxplot？

Answer 1

嘗試是這樣的

boxplot(unlist(theData))

如何使用melt功能reshape轉換您的數據爲「長」格式，然後使用上boxplot？假設你的數據在一個對象命名df：

> library(reshape) 
> df.m <- melt(df) 
Using as id variables 
> head(df.m) 
    variable value 
1 X20.7 99.64920 
2 X20.7 98.76469 
3 X20.7 98.37824 
4 X20.7 98.11356 
5 X20.7 97.80027 
6 X20.7 97.47825
