A matrix is a two dimensional array of data. The

following is a matrix with 2 rows and 3 columns.

> x<-matrix(1:6,byrow=T,nrow=2,ncol=3)

> x

     [,1] [,2]

[,3]

[1,]    1    2   

3

[2,]    4    5   

6

Here matrix is filled row wise.

 

Using

Dimension:

> x<-1:12

> dim(x)<-c(3,4)

> x

     [,1] [,2]

[,3] [,4]

[1,]    1    4   

7   10

[2,]    2    5   

8   11

[3,]    3    6   

9   12

By default, the matrix is filled column wise.

Using

array() function:

> x<-array(1:12,dim=c(3,4))

> x

     [,1] [,2]

[,3] [,4]

[1,]    1    4   

7   10

[2,]    2    5   

8   11

[3,]    3    6   

9   12

Here dimensions are mentioned by (3 by 4) by dim argument.

 

> x<-matrix(1:12,3,4,1)

> x

     [,1] [,2]

[,3] [,4]

[1,]    1    2   

3    4

[2,]    5    6   

7    8

[3,]    9   10  

11   12

The value ‘1’ can be used to get the same result

replacing the argument ‘byrow=T’.
