如何在R中分配2個向量中的字符串

Question

我與R et Rstudio一起工作，我遇到了問題。

首先，我有2個向量：

cap-color    
cap-color    
odor      
odor      
odor      
odor      
gill-spacing    
gill-size    
gill-color    
stalk-surface-above-ring 
stalk-color-above-ring 
spore-print-color  
spore-print-color  
population    
population 

AND：

buff  
pink  
creosote 
foul  
musty  
pungent 
close  
narrow 
buff  
silky  
cinnamon 

chocolate 

green  

scattered 

several 

現在，我想的輸出：

cap-color ∈ {buff, pink} 
odor ∈ {creosote, foul, musty, pungent} 
gill-spacing = {close} 
gill-size = {narrow} 
gill-color = {buff} 
stalk-surface-above-ring = {silky} 
stalk-color-above-ring = {cinnamon} 
spore-print-color ∈ {chocolate, green} 
population ∈ {scattered, several} 

Answer 1

使之成爲data.table然後粘貼矢量2通過矢量分組的元素1

library(data.table) 
dt <- data.table("Name"=vector1,"Var"=vector2) 
res <- dt[,paste(Var,collapse=","),by=Name] 

res 
        Name       V1 
1:    cap-color     buff,pink 
2:      odor creosote,foul,musty,pungent 
3:    gill-spacing      close 
4:    gill-size      narrow 
5:    gill-color      buff 
6: stalk-surface-above-ring      silky 
7: stalk-color-above-ring     cinnamon 
8:  spore-print-color    chocolate,green 
9:    population   scattered,several 

下一次給予在實際r輸出格式，列表或數據幀中的期望的輸出例如
