Question

我对R很新，需要社区帮助解决我的问题。

我有这组数据，我计划堆积条形图。

date        id  column1 column2     
2015-09-01  206 96301   91807    
2015-09-02  206 87543   88082    
2015-09-03  206 87636   89064   
2015-09-04  206 95445   93241    
2015-09-05  206 93510   93640   
2015-09-06  206 153797  106226

我理解它的方式，我需要将此数据帧转换为宽格式。我试图重新塑造它，但似乎并没有像我需要的那样重塑它。

是否可以将其重塑为此格式：

date id 2015-09-01  2015-09-02  2015-09-03  2015-09-04  2015-09-05  2015-09-06
column1 96301   87543   87636   95445   2156-01-07  153797  
column2 91807   88082   89064   93241   93640   106226

Answer 1

您可以使用t()功能转换数据。

> A <- matrix(c("2015-09-01","2015-09-02","2015-09-03","2015-09-04","2015-09-05","2015-09-06"), ncol = 6)
> B <- matrix(c(96301,87543,87636,95445,93510,153797), ncol = 6)
> C <- matrix(c(91807,88082,89064,93241,93640,106226), ncol = 6)
> AB <- rbind.fill.matrix(A,B, C)
> AB <- t(AB)
> colnames(AB) <- c("Col1", "Col2", "Farm")
> 
> AB
  Col1         Col2     Farm    
1 "2015-09-01" "96301"  "91807" 
2 "2015-09-02" "87543"  "88082" 
3 "2015-09-03" "87636"  "89064" 
4 "2015-09-04" "95445"  "93241" 
5 "2015-09-05" "93510"  "93640" 
6 "2015-09-06" "153797" "106226"

现在你可以使用t（）函数。

> t(AB)
     1            2            3            4            5            6           
Col1 "2015-09-01" "2015-09-02" "2015-09-03" "2015-09-04" "2015-09-05" "2015-09-06"
Col2 "96301"      "87543"      "87636"      "95445"      "93510"      "153797"    
Farm "91807"      "88082"      "89064"      "93241"      "93640"      "106226"

要创建堆积条形图，我建议您查看this page。它详细说明了如何创建多个不同的（条形）图表

希望这有助于你！
