Combining 3 arrays by row number

Question

Is there a way to combine three arrays in R so that the first row of the first array is followed by the first row of the second array and that is followed by the third row of the third array? So, if I ran the following code:

> number1<-rbind(rep("A",3), rep("B",3), rep("C",3))
> number1
     [,1] [,2] [,3]
[1,] "A"  "A"  "A" 
[2,] "B"  "B"  "B" 
[3,] "C"  "C"  "C" 
> number2<-rbind(rep(1,3), rep(2,3), rep(3,3))
> number2
     [,1] [,2] [,3]
[1,]    1    1    1
[2,]    2    2    2
[3,]    3    3    3
> number3<-rbind(rep("X",3), rep("Y",3), rep("Z",3))
> number3
     [,1] [,2] [,3]
[1,] "X"  "X"  "X" 
[2,] "Y"  "Y"  "Y" 
[3,] "Z"  "Z"  "Z"

The result would look like this:

      [,1] [,2] [,3]
 [1,] "A"  "A"  "A" 
 [2,] "1"  "1"  "1" 
 [3,] "X"  "X"  "X" 
 [4,] "B"  "B"  "B" 
 [5,] "2"  "2"  "2" 
 [6,] "Y"  "Y"  "Y" 
 [7,] "C"  "C"  "C" 
 [8,] "3"  "3"  "3" 
 [9,] "Z"  "Z"  "Z"

I have tried melt but I can't get it to work.

Answer 1

You could try this:

> matrix(t(cbind(number1,number2,number3)),ncol=3, byrow=T)
#      [,1] [,2] [,3]
# [1,] "A"  "A"  "A" 
# [2,] "1"  "1"  "1" 
# [3,] "X"  "X"  "X" 
# [4,] "B"  "B"  "B" 
# [5,] "2"  "2"  "2" 
# [6,] "Y"  "Y"  "Y" 
# [7,] "C"  "C"  "C" 
# [8,] "3"  "3"  "3" 
# [9,] "Z"  "Z"  "Z"
