Module # 5 Doing Math

This week we are looking at matrixes and doing some math with them. To start with we have A which is a 10*10 and B which is a 100*10 matrix(not shown).


With the instructions to find the inverse if we used solve(A) it would fail because the determinate is 0.

"Error: system is computationally singular"

B would fail because it is not square. 

There were other instructions like performing multiplication with the Matrixes. for example multiplying the two matrixes together would require inverting B so it is a 10*100 because the inner dimensions need to match. The first few rows of that math are here, the resulting vector is also 10x100.

Assignment #10: Building Your Own R Package

The purpose of my blog this week is to build a  draft a proposal describing: The purpose and scope of your package (who will use it and why). The idea would be for small businesses to quickly sort and predict where volume of orders are being shipped most often. Key functions you plan to implement (name + brief description). clean address sort labels by region determine where most your key shipping locations are. How you chose the fields in  DESCRIPTION  (dependencies, license, authors). Package: Friedman Title: What the Package Does (One Line, Title Case) Version: 0.0.0.9000 Authors@R:      person("Zachary", "Wright", , "zakkwright@yahoo.com", role = c("aut", "cre")) Description: "Tools for organizing and analyzing shipping and order data for small collectible businesses.  With the intention of " License: `use_mit_license()`, `use_gpl3_license()` or friends to pick a     license Encoding: UTF-8 Roxygen: list(markdown = TRUE...

Module # 7 R Object: S3 vs. S4 assignment

  How do you tell what OO system (S3 vs. S4) an object is associated with?          Y ou can check an Objects class using  class(object_name) in order to determine if its S3 or S4. If an object has a formal class definition then it is S4. Most base R objects are S3 How do you determine the base type (like integer or list) of an object? You can use the command typeof() in order to get a readout of what type an object is. For instance class(mtcars) will give you a readout "data.frame" but typeof(mtcars) will give you the base type list.  What is a generic function? A generic function is a function that performs differently depending on the class. R actually decides what the function does for you in a process called method dispatch. methods() will list all the options the function could perform some examples of generics print() summary() plot() mean() head() tail() str() What are the main differences between S3 and S4? S3 is a simple and informa...

Week 3

Image
 This week is about comparing Election poll Results. To start with arranging the 3 variables into a data frame provides us with this. Name ABC_poll_results CBS_poll_results 1 Jeb 4 12 2 Donald 62 75 3 Ted 51 43 4 Marco 21 19 5 Carly 2 1 6 Hillary 14 21 7 Berine 15 19 We can look at the differences between the two polls. Name ABC_poll_results CBS_poll_results Difference 1 Jeb 4 12 -8 2 Donald 62 75 -13 3 Ted 51 43 8 4 Marco 21 19 2 5 Carly 2 1 1 6 Hillary 14 21 -7 7 Berine 15 19 -4 We can also clearly ...
