Method: Use dim() Function

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.
