Installation Report

 

Installation Report

When switching from an Android device to macOS, I had to be careful during the first-time installation of R and RStudio because the setup process is different on Mac computers. One challenge I encountered was selecting the correct R installer, as CRAN provides versions tailored for both Intel and Apple Silicon Macs. Initially, I almost chose the Intel version, but after checking my Mac's specifications, I realized that the arm64 version was needed for Apple Silicon. Additionally, macOS displayed security warnings when I first opened RStudio, which made the process a bit confusing. 

Resolutions and Verification

To address these issues, I downloaded the R-4.5.1-arm64.pkg installer, which is optimized for Apple Silicon hardware, and reinstalled R without further complications. For RStudio, I navigated to System Settings → Privacy & Security and allowed it to open despite the warning. Once both R and RStudio were open, I verified their functionality by running the commands R.version.string and RStudio.Version()$version in the RStudio Console. These commands confirmed that the latest versions were installed correctly and were operating properly on my Mac.

System Details

  • Operating System: macOS Sequoia 15.6.1

  • R version: 4.5.1 (Apple Silicon build, arm64)

  • RStudio version: 2025.05.1.513 (released June 5, 2025)

Below is a screenshot showing my RStudio console where I run R commands and view outputs.

Assignment 5: Matrix Algebra in R For this assignment, I explored how to create and inspect matrices in R, how to compute matrix inverses and determinants, and how to handle errors when working with non-square matrices. I also reflected on issues of numeric stability and performance that arise in matrix algebra computations. R Code # 1. Create the matrices A <- matrix(1:100, nrow = 10) B <- matrix(1:1000, nrow = 10) # 2. Inspect dimensions dimA <- dim(A) # should be 10 × 10 dimB <- dim(B) # should be 10 × 100 print("Dimensions of A:") print(dimA) print("Dimensions of B:") print(dimB) # 3. Compute inverse and determinant for A invA <- solve(A) detA <- det(A) print("Inverse of A:") print(invA) print("Determinant of A:") print(detA) # 4. Handle non-square matrix B with tryCatch invB <- tryCatch(solve(B), error = function(e) e) detB <- tryCatch(det(B), error = function(e) e) print("Inverse of B attempt:") print...

  Assignment 6: Matrix Operations and Construction In this assignment,  I practiced creating and manipulating matrices in R. The goal was to strengthen my understanding of how R handles matrix operations such as addition, subtraction, diagonal construction, and combining blocks of matrices to form structured arrays. R Code 🔹 Task 1: Matrix Addition & Subtraction # Task 1: define A and B A <- matrix(c(2, 0, 1, 3), ncol = 2) B <- matrix(c(5, 2, 4, -1), ncol = 2) # Addition A_plus_B <- A + B print("A + B:") print(A_plus_B) # Subtraction A_minus_B <- A - B print("A - B:") print(A_minus_B) 🔹 Task 2: Create a Diagonal Matrix # Task 2: Create a Diagonal Matrix D <- diag(c(4, 1, 2, 3)) print("Diagonal Matrix D:") print(D) 🔹 Task 3: Construct a Custom 5×5 Matrix # Task 3: Construct a Custom 5x5 Matrix # Step 1: create the first row row1 <- c(3, 1, 1, 1, 1) # Step 2: create the remaining rows: # - first column all 2’s (rows 2–5) # - diagonal...

Assignment 2

  Assignment 2 - Importing Data and Function Evaluation in R For this part of the assignment, I tested the provided myMean function in RStudio, carefully recorded the errors that appeared, explained why they happened, and then corrected the code so it would successfully return the mean of the given dataset. Original Code:  assignment2 <- c(16, 18, 14, 22, 27, 17, 19, 17, 17, 22, 20, 22) myMean <- function(assignment2) {       return(sum(assignment) / length(someData))  }  Errors from Testing Error 1: > return(sum(assignment) / length(someData))  Error: object 'assignment' not found  Inside the function body, the code used assignment instead of assignment2. Since no variable named assignment exists, R could not evaluate the expression and produced this error. Error 2: > return(sum(assignment2) / length(someData))  Error: object 'someData' not found  Here, assignment2 was corrected in the sum() part, but t...
