R Data Frames:

In R, a data frame is like a table or a spreadsheet in which you can store data. It's a two-dimensional data structure where rows represent observations and columns represent variables or attributes.

Let's understand data frames with an example:

In this example:

• We use the data.frame() function to create a data frame.
• Inside the function, we specify the columns of the data frame along with their values.
• Each column is represented by a vector of values, such as names, ages, genders, and marital statuses.
• We assign the resulting data frame to the variable my_df.
• Finally, we print the data frame.

The resulting data frame will look like this:

Each row represents an observation (e.g., a person in this case), and each column represents a variable or attribute (e.g., name, age, gender, marital status).

Data frames are widely used for data analysis, manipulation, and visualization in R. They provide a convenient way to work with structured data, such as data imported from spreadsheets, databases, or other sources.
