Example
Enter the following code snippet:
# Creating the data frame.
emp.data <- data.frame(
emp_id = c (1:5),
emp_name = c("Robert","Dharam","Mini","Sharan","Garima"),
salary = c(20000.5,35000.2,60000.0,70000.0,84253.25),
start_date = as.Date(c("2011-01-21", "2013-11-03", "2014-01-25", "2014-07-21",
"2015-05-17")),
stringsAsFactors = FALSE
)
# Printing the data frame.
print(emp.data)
On execution of the above code, the following result is shown:
6.11.3 getting the structure of the Data Frame
The structure of the data frame can be seen by using the str() function.
