I am interested in knowing the difference between loading the whole entire data frame and inspecting the first couple of columns by using the head() function.

stud,

You don’t load the head of the data frame, you only view it. That is, the head is the first six rows of the data frame (by default). If there are fewer than six rows, you only view those rows.

You load the entire data frame, then view the head.

In more detail: The head displays all of the columns of the first six rows. If you would like to view more rows with the head() function, you simply put the number of rows you want to view in the head() function, like this – head(df, 10) for the first ten rows. You can optionally view the tail with the command using analogous syntax.
