Answer:
Voter registration lists, also called voter rolls, are the gateway to voting because a citizen typically cannot cast a vote that will count unless his or her name appears on the voter registration rolls. State and local officials regularly remove—or purge—citizens from voter rolls. In fact, 39 states and the District of Columbiareported purging more than 13 million voters from registration rolls between 2004 and 2006.
Explanation:
A list is an R-object that can have a wide range of different items inside of it, including vectors, functions, and even another list.
The head() function lets you display the first observations in a data frame. The method tail() prints the final observations in your data collection in a manner similar to that. Both head() and tail() print a top line called the 'header', which contains the names of the distinct variables in your data collection. The R language's transform() function is used to alter data. The first parameter is transformed into a data frame. A suitable variable name comprises of letters, numbers and the dot or underline characters. The variable name does not begin with a number but rather with a letter or a dot.
