Creating a Data Frame in R

A data frame is a matrix-like structure to store data tables. It is a list of vectors of equal length whose columns can be of differing data types

Problem:

Create a Data Frame in R

Solution:

A data frame has the variables of a data set as columns and the observations as rows. Now we  can create three vectors as below:

  • A character vector

  • A numeric vector

  • A logical vector

Then, will combine the three vectors into a data frame using the following code:

While working with Data Frames, we may need to work with an extremely large data set. For example, we can use the built-in data frame mtcars. 

If the dataset is huge, we may see only a part of the data in the console. we can use the below functions for better understanding.
head(): shows the first observations of a data frame.
tail(): prints out the last observations in your data set.
str(): shows you the structure of your data set
