For this assignment, I worked on importing data into RStudio and practicing basic R programming by testing and debugging a user-defined function. The goal was to understand how R functions handle variables and why correct naming is important. I started by creating a numeric vector in RStudio called assignment2, which contains twelve values. This vector was used as the input for testing the function. Next, I tested the provided myMean function by running myMean(assignment2) in the R console. Instead of returning a number, R produced an error.


The function failed because it referenced variables that did not exist. Although the function argument was named assignment2, the function body used the names assignment and someData. Since R functions can only access variables passed into the function or defined within it, this mismatch caused the error. To fix the problem, I updated the function so that it consistently used the argument name assignment2 when calculating the sum and length of the data. After correcting the variable names, the function successfully returned the mean. 

assignment2 <- c(16, 18, 14, 22, 27, 17, 19, 17, 17, 22, 20, 22)

myMean <- function(assignment2) {return(sum(assignment2) / length(assignment2))}

myMean(assignment2)

Assignment #5

 For Module #5, I practiced matrix operations in R and checked whether two matrices could be inverted. First, I created the matrices using the assignment instructions: A <- matrix(1:100, nrow = 10) and B <- matrix(1:1000, nrow = 10) . I used dim(A) and dim(B) to confirm their sizes. Matrix A is a 10×10 square matrix, while matrix B is a 10×100 matrix, which means B is not square. Next, I calculated the determinant of A using det(A) . The determinant came out to be 0 , which tells me A is singular . A singular matrix does not have an inverse, so when I attempted solve(A) R returned an error (I used tryCatch() to capture the error message without stopping my code). I also attempted solve(B) , but that also produced an error because non-square matrices do not have inverses . So the results were expected: A cannot be inverted because its determinant is 0, and B cannot be inverted because it is not square. After checking inverses, I explored additional matrix operations to ...

Assignment #4

 This assignment used a dataset from a local hospital that recorded information on ten patients. The variables included frequency of hospital visits in the past year, blood pressure measurements, the first doctor’s assessment, the second doctor’s assessment, and the final emergency decision. The data was entered into R as vectors and combined into a data frame. A boxplot and histogram were created to visualize the blood pressure values for the patients. The histogram showed that most patients had moderate blood pressure readings, while a few had very high values such as 176 and 205. The boxplot highlighted these extreme readings as outliers compared to the rest of the group. The majority of patients fell within a lower to mid-range of blood pressure, but the spread of values showed that there was significant variation across the ten patients. Patients with higher blood pressure readings were more likely to receive a high final decision for immediate care. When both doctors rated ...

Assignment 10

 For this assignment, I created my first R package called Friedman , which is designed to provide simple tools for data visualization and basic analysis. The goal of this package is to make working with data easier, especially for students or beginners who may find R overwhelming at first. Instead of writing long lines of code, users can quickly generate visuals and explore datasets using simple functions. One of the main functions included is plot_summary() , which creates a scatter plot using ggplot2 with minimal input. Overall, the package focuses on simplicity, efficiency, and making data exploration more accessible. The DESCRIPTION file plays an important role in defining the structure and purpose of the package. I included key fields such as the package name, version (0.0.0.9000 for development), and a short description explaining what the package does. I listed myself as both the author and creator using the Authors@R field, and included dependencies like ggplot2 and dplyr ...
