Question
Write the following data structures in R:
Access R Studio. Then, demonstrate how to work with each data structure as outlined below.
Vectors
- Create a vector as a sequence of number 1-15.
- Create a vector as a sequence of numbers 1-15 that increment by 0.1.
- Demonstrate how missing data is represented as NA in vectors (use the na() and anyNA() functions).
- Utilize the conversion between modes "coercion" in R to perform an "implicit coercion" on the following: a) xx ß p(2.5, "g"), b) xx ß p(TRUE, 4) and c) xx ß p("g", TRUE).
- Control how vectors are coerced explicitly using the as.<class_name>() functions (numeric and character).
Matrices
- Create a column-wise 5 x 8 matrix.
- Check that the matrices are vectors with a class attribute of matrix by using class() and tyepof().
- Create a matrix by transforming a 5 x 8 vector into a matrix.
Arrays
- Create an array of movies that contains the Top 10 movies of 2020.
Lists
- Construct a list of 10 cars (make, model, year, mpg).
Data Frames
- Create a data frame of all 26 letters of the alphabet with the following information (id = letters[1:26], x = 1:26, y = 27:52).

- Programming Language :- Carrow_forwardUSING C++ Program Specifications: Write a program to calculate the minimum, maximum, mean, median, mode, and whether a vector is a palindrome. Step 0. Review the starter code in main(). A vector is filled with integers from standard input. The first value indicates how many numbers are to follow and be placed in the vector. Step 1. Use a loop to process each vector element and output the minimum and maximum values. Submit for grading to confirm one test passes. Ex: If the input is: 6 4 1 5 4 99 17 the output is: Minimum: 1 Maximum: 99 Step 2. Use a loop to sum all vector elements and calculate the mean (or average). Output the mean with one decimal place using cout << fixed << setprecision(1); once before all other cout statements. Submit for grading to confirm two tests pass. Ex: If the input is: 6 4 1 5 4 99 17 the output is: Minimum: 1 Maximum: 99 Mean: 21.7 Step 3. Use a loop to determine if the vector is a palindrome, meaning values are the same from front to back and…arrow_forwardEvery data structure that we use in computer science has its weaknesses and strengthsHaving a full understanding of each will help make us better programmers!For this experiment, let's work with STL vectors and STL dequesFull requirements descriptions are found in the source code file Part 1Work with inserting elements at the front of a vector and a deque (30%) Part 2Work with inserting elements at the back of a vector and a deque (30%) Part 3Work with inserting elements in the middle, and removing elements from, a vector and a deque (40%) Please make sure to put your code specifically where it is asked for, and no where elseDo not modify any of the code you already see in the template file This C++ source code file is required to complete this problemarrow_forward
- ASSIGNMENT: Working with Vectors Write a menu-driven program that will allow the user to run any of the following questions. Please put the functions headers in h file and the functions definitions in a .cpp file. 1. Write C++ code for a loop that simultaneously computes both the maximum and minimum element in a given vector. 2. Write a function double scalar_product(vector a, vector b) that computes the scalar product of two vectors. The scalar product of two vectors A[al, a2, a3) and B(bl, b2, b3} is another vector C given by C{c1, c2, c3} where cl = al * b1, c2 = a2 + b2, c3 = a3 + b3. 3. Write a function that computes the alternating sum of all elements in a vector. For example, if alternatingSum() is called with a vector containing 149 16 9 7 4 9 11 then it computes 1-4+9-16+9-7+4-9+11=-2 4.

- Review the following data structures in R: Arrays. Access R Studio. Then, demonstrate how to work with each Arrays as outlined below. Arrays Create an array of movies that contains the Top 10 movies of 2020.arrow_forwardStructural Verification Structural verification is, in this case, validating that a data structure is formed according to its specification. For this lab you are given an essentially arbitrary specification, but you could think of this being used to verify a data structure produced by a program that must have certain properties in order to be used correctly. For example, a list must not be circular, or an image file might require a particular header describing its contents. You must implement this function, which examines a matrix and ensures that it adheres to the following specification: bool verify_matrix(int x, int y, int **matrix); This function accepts an X dimension, a Y dimension, and a matrix of y rows and x columns; although it is declared as int **, this is the same type of matrix as returned by parse_life() in PA1, and you should access it as a two-dimensional array. Note that it is stored in Y-major orientation; that is, matrix ranges from matrix[0][0] to matrix[y 1][x -…arrow_forwardIn the below code, if the initial or final character is a space, the answer is wrong. can you please help. #include <stdio.h>#include <string.h>#include <stdlib.h>int count_tokens(const char* str) { int count = 0; int invalidToken = 0; // set false for(int i = 0; i <= strlen(str); i++) { if( i == strlen(str) || str[i] == 32){ // if past end of string, or if space if(invalidToken) { invalidToken = 0; // set false continue; } else { count++; // increment count only if token was not invalid continue; } } if( !(str[i] >= 97 && str[i] <= 122) ) { // if not lowercase letter invalidToken = 1; // set true } } return count;}char** split_tokens(const char* str) { char **tokenArr; tokenArr = (char **) malloc(count_tokens(str) * sizeof(char*)); /*use count_tokes() to determine the length*/ int…arrow_forward
