如何直接输入数据以生成表示列联表的data.frame？

Question

我试图直接将以下数据输入R(代表一个列联表)

Area        School    Coffeshop    Hospitals    Parks    Totatl  
Washington     142          120           20       20       302   
Seattle        120          140           30       40       330 
Total          262          260           50       60       632

我的代码是这样的:

n<-c("Area","School","Cofeeshop","Hospitals","Parks","Total") 
x<-c("Washington",142,120,20,20,302)
y<-c("Seattle",120,140,30,40,330)
z<-c("Total",262,260,50,60,631)
data<-cbind(n,x,y,z)
data<-data.frame(data)

您的代码中充满了基本的语法错误,请尝试直接从您使用的脚本中进行复制和粘贴.(我真的希望你这里没有这样做).

如果在同一向量中组合字符和数字变量,它将创建一个字符向量,这不是您想要的.

尝试类似的东西

vec_names <-c("School", "Cofeeshop", "Hospitals", "Parks", "Total") 
Washington <- c(142, 120, 20, 20, 302)
Seattle<-c(120, 140, 30, 40, 330)
Total <-  c(262, 260, 50, 60, 631)

ctable <- rbind(Washington, Seattle, Total)
colnames(ctable) <- vec_names

# ctable is a matrix at the moment, with the rownames identifying 
# Washington etc

ctable_df <- data.frame(ctable)

# ctable_df is now a data.frame.
# if you want area as a column in your data.frame (not just row.names)
CTABLE <- data.frame(area= rownames(ctable_df), ctable_df, row.names = NULL)
CTABLE
        area School Cofeeshop Hospitals Parks Total
1 Washington    142       120        20    20   302
2    Seattle    120       140        30    40   330
3      Total    262       260        50    60   631
