For this exercise, we’ll use the (built-in) dataset VADeaths. a) Make sure the object is a data frame, if not change it to a data frame. b) Create a new variable, named Total, which is the sum of each row. c) Change the order of the columns so total is the first variable.

- For this project you will be implementing a new data structure called LinkedGrid. This is a linked type data structure version of a 2D array. The LinkedGrid can support any combination of dimensions (n x n, n x m, or m x n, where n > m) This data structure has a singly linked system which allows you to traverse the grid in multiple directions in addition to allowing you to retrieve specific rows and columns. The following diagram gives a rough visual of this data structure. NOTE: Your LinkedGrid MUST work with any number of nodes, the picture only shows twelve as an idea. You may not hardcode only twelve nodes... There should be no public functions other than the ones given to you You may implement any other private functions you feel are necessary to help you implement the given constructors / public functions Complete ALL methods with "TO DO" in LinkedGrid.java import java.util.ArrayList; public class LinkedGrid<E>{private int numRows;private int numCols; private…arrow_forwardQuestion on R Studio Please provide as detailed explanation as possible, with examples if possible.

Drop the features 'day', 'ISI', 'DC', 'RH', and 'FFMC' from the data using the drop_features keyword argument.

- javascript5. Create a function that reverses an array This challenge is particularly helpful if you're planning to become a Data Scientist. Manipulating data is a significant part of the role, and building the foundations now will help you later down the road when you're working with large databases. Start small here and work your way up. Begin with an array of 5 numbers, and then try your program with a larger array to verify its success.arrow_forwardRight now we have a CourseListType that will hold a static 50 courses. Now we need to make that a little more flexible. To do that we want to change the static array to a dynamic array. So, what do we need to do? Modify CourseListType so that it contains a pointer to a CourseType rather than an array of CourseType. Modify the CourseListType constructor to create a dynamic array allocating space for a specific number of CourseType elements rather than always using 50. (Note: This is still not totally flexible, but is much better than a static limit.) Finally, we need to create a destructor to for CourseListType to deallocate space whenever a declared object goes out of scope.) //courseListType.h file #ifndef COURSELISTTYPE_H_INCLUDED#define COURSELISTTYPE_H_INCLUDED #include <string>#include "courseType.h" class courseTypeList { public:void print() const;void addCourse(std::string);courseTypeList(); private:static const int NUM_COURSES = 50;int courseCount;courseType…arrow_forwardAdd code to Insertion and Selection to make them draw thearray contents as vertical bars like the visual traces in this section, redrawing the barsafter each pass, to produce an animated effect, ending in a “sorted” picture where thebars appear in order of their height. Hint : Use a client like the one in the text that generates random Double values, insert calls to show() as appropriate in the sort code, andimplement a show() method that clears the canvas and draws the bars.arrow_forward

- Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10), print: 7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. 1 #include HNm in 10 m DO G 2 3 int main(void) { 4 5 6 const int NUM_VALS = 4; int courseGrades [NUM_VALS]; int i; 7 8 for (i = 0; i < NUM_VALS; ++i) { scanf("%d", &(courseGrades[i])); 9 } 10 11 12 13 14 15 } /*Your solution…arrow_forwardUse import sys. Use the fastfood.csv file to complete the following assignment. Create a file, fastfood.py, that loads the .csv file and runs a regression predicting calories from total_fat, sat_fat, cholesterol, and sodium, in that order. Add a constant using sm.add_constant(data). Note: you will not need to upload the .csv to CodeGrade because I have pre-loaded it, but you will need to read in the data. Then, print the following to two decimals print(model.mse_total.round(2)) print(model.rsquared.round(2)) print(model.params.round(2)) print(model.pvalues.round(2))arrow_forwardPlease please with this using javaarrow_forward
