# [R] create one bigger matrix with one smaller matrix

```Dear R users,

Suppose that I have a matrix A

A <- matrix(c(1,2,3,4),2,2)
> A
[,1] [,2]
[1,]    1    3
[2,]    2    4

With this matrix A, I'd like to create bigger one, for example,

[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12] [,13]
[,14]
[1,]    1    3    1    3    1    3    1    3    1     3     1     3
1     3
[2,]    2    4    2    4    2    4    2    4    2     4     2     4
2     4
[3,]    1    3    1    3    1    3    1    3    1     3     1     3
1     3
[4,]    2    4    2    4    2    4    2    4    2     4     2     4
2     4
[5,]    1    3    1    3    1    3    1    3    1     3     1     3
1     3
[6,]    2    4    2    4    2    4    2    4    2     4     2     4
2     4
[7,]    1    3    1    3    1    3    1    3    1     3     1     3
1     3
[8,]    2    4    2    4    2    4    2    4    2     4     2     4
2     4
[9,]    1    3    1    3    1    3    1    3    1     3     1     3
1     3
[10,]    2    4    2    4    2    4    2    4    2     4     2     4
2     4
[11,]    1    3    1    3    1    3    1    3    1     3     1     3
1     3
[12,]    2    4    2    4    2    4    2    4    2     4     2     4
2     4
[13,]    1    3    1    3    1    3    1    3    1     3     1     3
1     3
[14,]    2    4    2    4    2    4    2    4    2     4     2     4
2     4

In fact, I want much bigger one. I wonder if there is an elegant way to do
this?

Any suggestions? Thank you!

Best wishes and Happy new year
