How to print matrix without line numbers in R?
To print matrix without line numbers in R, we can follow the below steps −
First of all, create a matrix.
Then, print the matrix with as.data.frame and row.names argument set to FALSE.
Example1
Create the matrix
Let’s create a matrix as shown below −
Live Demo
M1<-matrix(rpois(60,5),ncol=3)
M1
On executing, the above script generates the below output(this output will vary on your system due to randomization) −
Output
[,1] [,2] [,3]
[1,] 9 4 2
[2,] 3 4 7
[3,] 3 3 4
[4,] 3 9 8
[5,] 4 3 7
[6,] 6 8 5
[7,] 9 5 3
[8,] 2 1 6
[9,] 1 8 7
[10,] 8 3 5
[11,] 3 6 5
[12,] 8 4 5
[13,] 6 6 4
[14,] 2 3 2
[15,] 3 5 3
[16,] 5 11 7
[17,] 4 4 7
[18,] 2 4 4
[19,] 4 7 4
[20,] 6 5 7
Removing line numbers from the matrix
Using as.data.frame function and print function to print the matrix M1 without line
numbers −
Live Demo
M1<-matrix(rpois(60,5),ncol=3)
print(as.data.frame(M1),row.names=F)
Output
V1 V2 V3
9 4 2
3 4 7
3 3 4
3 9 8
4 3 7
6 8 5
9 5 3
2 1 6
1 8 7
8 3 5
3 6 5
8 4 5
6 6 4
2 3 2
3 5 3
5 11 7
4 4 7
2 4 4
4 7 4
6 5 7
Example 2
Create the matrix
Let’s create a matrix as shown below −
Live Demo
M2<-matrix(round(rnorm(80),1),ncol=4)
M2
On executing, the above script generates the below output(this output will vary on your system due to randomization) −
Output
[,1] [,2] [,3] [,4]
[1,] -0.7 0.9 0.3 -0.6
[2,] -1.0 -0.8 0.6 -1.3
[3,] -1.9 -1.2 -1.9 -0.8
[4,] -1.8 0.7 -1.7 -1.0
[5,] -2.1 -0.3 1.6 0.8
[6,] -1.1 -0.9 -1.7 -1.9
[7,] -0.1 1.5 -1.2 0.2
[8,] 0.5 -0.9 0.0 -0.3
[9,] 0.3 2.1 -0.2 1.0
[10,] 1.3 0.2 -0.6 0.5
[11,] -0.5 1.2 -0.8 -0.9
[12,] -1.7 -1.0 0.6 -0.2
[13,] 1.0 0.3 0.8 -0.1
[14,] -0.1 1.9 -2.3 -0.3
[15,] -0.5 -1.3 0.1 -0.7
[16,] 1.3 1.0 0.8 -0.5
[17,] 1.2 -0.4 2.4 0.3
[18,] 0.9 -1.1 0.4 -1.5
[19,] 0.6 -0.7 -2.7 1.1
[20,] -1.4 -0.5 0.5 -0.4
