Module 6 Assignment

 Module 6 Assignment


    This week I successfully followed the instructions for module 6. I created two matrices, A and B, and I added and subtracted them. Next, I built a matrix with 4,1,2,3 along the diagonal using the diag() function and using concatenation to get the numbers in the desired order. Lastly, I generated the desired matrix by creating matrix e with diagonal 3s with 4 rows and 4 columns (I figured out to start with a 4X4 to add the desired rows and columns to end in a 5X5). I added a row of 1s to the top and a column of 2s to the front using rbind() and cbind(). I learned that order in the arguments matters. Lastly, I changed the value in row 1 column 1 in matrix g to a 3. The result is the desired vector. 


    Creating the desired vector was the most difficult part of the assignment. I had to look through my notes on matrices to figure out the best functions to use to add the numbers. I also spent a lot of time figuring out in which order to add the numbers.

 Module 10 Assignment Github Repository:  https://github.com/christilly/readspeed/blob/main/DESCRIPTION R package idea     My idea for this R package is to glean fun and useful information from Goodreads data. Goodreads is a website/app for books where people can find new books track the books they read. People can download their Goodreads library directly from their accounts in the form of a CSV file. The CSV file contains the aforementioned information and more including ratings given to the books by the readers, books in the read and want to read sections of their accounts, IBSNs, and more. My idea is to create an R package where Goodreads users can upload their data and the program calculates the overall average time it takes for the user to finish a book, as well as the time it takes for the user to finish short, medium, and long books. This information can be useful for the user by giving an understanding of their reading habits.  Creating the R package ...
