The **nrow()** function is used to get number of rows in data frame, matrix or table like structure.

The following method shows how you can do it with syntax.

**Method: Use nrow() Function**

```
nrow(df)
```

Let’s see example using **nrow()** function.

## Use nrow() Function to Get Number of Rows of Data Frame

Suppose we have data frame and want to find number of rows of data frame:

```
# Create data frame
df <- data.frame(Machine_name=c("A","B","C","D","A","A","G","B"),
Temperature=c(12,9,NA,13,18,28,22,23),
Pressure=c(20,25,27,29,30,32,39,40))
# Find total number of rows
nrow(df)
```

Output:

```
[1] 8
```

Here the **nrow()** function return 8 because data frame having 8 rows.
