The **dim()** function is used to get dimension of data frame, matrix or array in R.

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

**Method: Use dim() Function**

```
dim(dataframe)
```

The following example shows how you can use the dim() function in R.

## Use dim() Function to Get Dimension of Data Frame

Let’s apply **dim()** function on data frame:

```
# Create data frame
df <- data.frame(Machine_name=c("A","B","C","D","E","F"),
Pressure=c(78.2, 71.7, 80.21, 83.12, 82.56, 79.50),
Temperature=c(31, 35, 36, 36, 38, 32),
Status=c(TRUE,TRUE,FALSE,FALSE,FALSE,TRUE))
# Calculate diamension
d <- dim(df)
# Print diamension
print(d)
```

Output:

```
[1] 6 4
```

The output shows total number of rows and column of data frame.
