Showing the first and last rows of a dataset in R is a simple process that can be done using the head() and tail() functions. In this essay, we will go over the steps needed to show the first and last rows of a dataset in R.

The first step is to load the dataset into R. This can be done using the read.csv() function, which allows you to load data from a CSV file, or by using the read.table() function, which allows you to load data from a tab-separated file. Once the data is loaded, it’s important to make sure that the variables are in the correct format, such as numeric for continuous variables and factors for categorical variables.

The next step is to show the first and last rows of the dataset. The head() function is used to show the first n rows of a dataset, where n is an integer that can be specified as an argument. For example, head(data, n = 10) will show the first 10 rows of the dataset. By default, the head() function shows the first 6 rows of the dataset.

The tail() function is used to show the last n rows of a dataset, where n is an integer that can be specified as an argument. For example, tail(data, n = 10) will show the last 10 rows of the dataset. By default, the tail() function shows the last 6 rows of the dataset.

It’s important to note that the head() and tail() functions return the first and last rows of the dataset, respectively, but they don’t modify the original dataset. If you want to remove or keep the first or last rows of the dataset, you can use the subset() function.

In conclusion, showing the first and last rows of a dataset in R is a simple process that can be done using the head() and tail() functions. The head() function is used to show the first n rows of a dataset, and the tail() function is used to show the last n rows of a dataset. Both functions have an argument n, which allows you to specify the number of rows to show, by default they show the first 6 and last 6 rows of the dataset respectively. It’s important to note that the head() and tail() functions return the first and last rows of the dataset, respectively, but they don’t modify the original dataset. If you want to remove or keep the first or last rows of the dataset, you can use the subset() function.
