** row()** function in R Language is used to get the row number of a matrix.

Syntax:row(x, as.factor=FALSE)

Parameters:

x:matrix

as.factor:a logical value indicating whether the value should be returned as a factor of column labels (created if necessary) rather than as numbers

**Example 1:**

`# R program to illustrate ` `# row function ` ` ` `# Initializing a matrix with ` `# 2 rows and 2 columns ` `x <` `-` `matrix(c(` `1` `, ` `2` `, ` `3` `, ` `4` `), ` `2` `, ` `2` `) ` ` ` `# Getting the matrix representation ` `x ` ` ` `# Calling the row() function ` `row(x) ` |

**Output:**

$Rscript main.r [, 1] [, 2] [1, ] 1 3 [2, ] 2 4 [, 1] [, 2] [1, ] 1 1 [2, ] 2 2

**Example 2:**

`# R program to illustrate ` `# row function ` ` ` `# Initializing a matrix with ` `# 3 rows and 3 columns ` `x <` `-` `matrix(rep(` `1` `:` `12` `), ` `3` `, ` `3` `) ` ` ` `# Getting the matrix representation ` `x ` ` ` `# Calling the row() function ` `row(x) ` |

**Output:**

[, 1] [, 2] [, 3] [1, ] 1 4 7 [2, ] 2 5 8 [3, ] 3 6 9 [, 1] [, 2] [, 3] [1, ] 1 1 1 [2, ] 2 2 2 [3, ] 3 3 3
