R 如何在数据帧的同一行中插入3个向量？

我是R的新手，有个问题。我创建了一个“空的”data.frame，因为在R中我不能这样做，我创建了一个向量来实现它，我将在完成脚本时删除它

x <- c("aa", 0, 0, 0, "zz") #Vector to fulfill the dataframe (it will be deleted at the end of the script)       
df <<- rbind(x) #Creating a matrix. See: class(df)    
df <<- data.frame(df) #Converting the matrix into a data.frame 

我试过：

df也许，你可以这么做

x <- c("aa", 0, 0, 0, "zz") 
a <- c("bb")       
b <- c(2, 3, 4)    
c <- c("yy")   
y <- c(a, b, c)
rbind(r1 = x,r2 =  y)


#   [,1] [,2] [,3] [,4] [,5]
#r1 "aa" "0"  "0"  "0"  "zz"
#r2 "bb" "2"  "3"  "4"  "yy"

也许，你可以这样做

x <- c("aa", 0, 0, 0, "zz") 
a <- c("bb")       
b <- c(2, 3, 4)    
c <- c("yy")   
y <- c(a, b, c)
rbind(r1 = x,r2 =  y)


#   [,1] [,2] [,3] [,4] [,5]
#r1 "aa" "0"  "0"  "0"  "zz"
#r2 "bb" "2"  "3"  "4"  "yy"

根据所需输出，您可以尝试以下方法：
并猜测您更想要的输出：
