Using dyplr for R:
Create data frame where each student is represented once.
Example of what I have:
| student | test | score |
| 1 | 1 | 4 |
| 1 | 2 | 5 |
| 1 | 3 | 6 |
What it should look like:
| Student | score 1 | score 2 | score 3 | score 4 |
|---|---|---|---|---|
| 1 | 4 | 5 | 6 | 8 |
| 2 | 1 | 5 | 6 | 8 |
| 3 | 4 | 3 | 6 | 9 |
| 4 | 2 | 3 | 4 | 5 |
Homework Answers
Solution:
Student = c(1, 2, 3, 4)
score1 = c(4, 1, 4, 2)
score2 = c(5, 5, 3, 3)
score3 = c(6, 6, 6, 4)
score4 = c(8, 8, 9, 5)
Students = data.frame(Student, score1, score2, score3,
score4)
print(Students)

Language is C programming Student ID should be 8 numbers long. create a program to read your student ID number and store it in an array. Input can not be hard wired, I have to be able to input my number Then change the first number to a letter. If the same number repeats in other parts of your student ID, you must change that number to a letter as well. print original array and modified array as your output....

Create a complete pseudo-code program in C++ to do the following using the PseudoCode language developed in class using Absolute Addressing. There is 1 deliverable: 1. You should include the input cards shown below as a test. THE PROGRAM: First you will read in a value N which holds the number of values to be read in. (so if N is 20 then there will be 20 more cards to read in.) Read in N values into an array. Bubble-Sort...

3. [25 points] Here's another example of using dynamic programming over intervals (like we saw with the RNA Secondary Structure problem) You're given an arithmetic expression consisting of positive integers separated by +s and s but without parentheses, and the goal is to determine the maximum possible value the expression could have by inserting parentheses in some way. For example, with 9-1+9-1 the max value is (9-1)(9-1) 16 (by the way, ((9-1)+9)-1 is an alternative parenthesization that achieves this value),...

c++ Instructions Overview In this programming challenge you will create a program to handle student test scores. You will have three tasks to complete in this challenge. Instructions Task 1 Write a program that allocates an array large enough to hold 5 student test scores. Once all the scores are entered, the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates the average score. The program should display the...

Python Help Create a program that outputs a table from 1 to 5 using what you've learned about "for" loops. Your program will print the number and indicate if the number is odd or even. If it is not odd you will multiply 2 numbers with it: number 1 and number 2. Your program must do the multiplication for only even numbers in the table. The output of your program should look like the figure below. Hint: Create a program...

I'm having problems with my pandas data frame. When I print my
data frame, it is appearing as one long column, instead of putting
the data side by side as in the left image. I'm working with
python. How do I fix this so that name, sex, and age appear side by
side like in image on left?
