Module 8: Input/Output, String Manipulation and 'plyr' Package In this weeks assignment, we used a variety of functions to import, define, modify and resave a dataset provided to us by using various functions to produce a filtered list of names and values to where that all members were organized by sex and by average grade, and then were filtered down using the grepl(), to students of both sexes that have an I or i in their name. Maintaining the same syntactical arguements, a resulting table entitled "DataSubset" was created and saved. I compiled into a .docx and will submit in canvas but here is the R script from RStudio: ##Module # 8 Input/Output, String Manipulation and plyr package. #This weeks assignment deals with a short process of importing, changing, cleaning and resaving data within R from a non-native filetype ##Add your libraries first ##Then, we must first import the data from what was provided to us in the instructions library(dplyr) library(plyr) librar...

 Module 8: Linear Regression Visualizations in ggplot2 DISCLAIMER: In this Week's submission, I will post the code and my comments here, but will submit a separate HTML .rmd file for your convenience in Canvas, so that viewing my work is easier since it will be organized into a compiled document. In this weeks module, we explored different styles of Statistical Analysis from a Dataset in R programming. The key, is to remember when dealing with data, what is the appropriate time to separate (use factor()) or to treat data irrespective of each other by allowing unfiltered data directly from the source to be visually represented. I used related columns from the data frame to visualize similarities and trends amongst characteristics of automobiles that I know for a fact can tell us about the others even without knowledge of their data. Without data, one might assume a larger engine means a quicker quarter mile or less fuel mileage, but that is not always the case. This data does not ta...

 Module 7: S3 and S4 I did what I could do and I am taking more time to understand how that the object oriented side of R works. I was very confused on this entire Module, but since that this is crucial information, review on my own time is how I see to remedy my lack of understanding. I saw that the assignment was due at 8PM instead of AM, I was not sure and decided to try as hard as I could until the end to understand what to do, when, why and how.  Questions: 1) S3 is quite generic and plain and is more of a 'one at a time' format where S4 has more formal classes that are inheritable and also can analyze and choose input from an array of arguments instead of a singular argument like S3 2) Using functions like class(), typeof() and even str() can help a user find out information about a dataframe 3) Generic Functions are like a universal, one size fits all type of function that can take a wide variety of input types and generate results.  4) As stated in quest...
