Importance of Variable Naming - Assignment 2

Today I tackled a function debugging exercise in R that taught me an important lesson about variable scope and naming consistency. I was given a vector of test data and a broken function to fix.


The Problem: The issue was inconsistent variable naming. While the function parameter was correctly named assignment2, inside the function body, the code referenced assignment (missing the "2") and someData (a completely different name). R couldn't find these variables because they simply didn't exist.


 What I Learned: This exercise reinforced how crucial attention to detail is in programming. A simple typo in a variable name can break an entire function, even when the logic is perfectly sound. It also highlighted the importance of understanding function scope in R - variables inside functions need to either be parameters, locally defined, or accessible from the global environment.

  RStudio Installation Experience Yesterday, I switched from Windows to Mac, which was new for me. Installing R and RStudio on macOS  It was simple, but I had to change some security settings in my Mac to allow the software to run.  I downloaded the correct files from the official sites, installed them, and opened RStudio successfully.  What is an R Vector? An R vector is a basic data structure that stores a sequence of elements all of the same type, such as  numbers, words, or logical values. It’s a core part of R because it allows you to organize and work with  data efficiently. Vectors are the foundation for many operations in R, making data manipulation and  analysis faster and easier. Vectors are essential in R because they enable you to perform operations on entire collections of data at  once, rather than handling each element individually. This makes your code more concise and efficient.  Understanding vectors is crucial because most ...

Code: # Task 1: Matrix Addition & Subtraction A = matrix(c(2, 0, 1, 3), ncol = 2) B = matrix(c(5, 2, 4, -1), ncol = 2) cat("Matrix A:\n") print(A) cat("\nMatrix B:\n") print(B) A_plus_B = A + B cat("\nA + B:\n") print(A_plus_B) A_minus_B = A - B cat("\nA - B:\n") print(A_minus_B) # Task 2: Create a Diagonal Matrix D = diag(c(4, 1, 2, 3)) cat("\nDiagonal Matrix D:\n") print(D) # Task 3: Construct a Custom 5x5 Matrix first_col = c(3, 2, 2, 2, 2) remaining_block = rbind(   c(1, 1, 1, 1),   diag(3, 4) ) custom_matrix = cbind(first_col, remaining_block) cat("\nCustom 5x5 Matrix:\n") print(custom_matrix) Output: > # Task 1: Matrix Addition & Subtraction > A = matrix(c(2, 0, 1, 3), ncol = 2) > B = matrix(c(5, 2, 4, -1), ncol = 2) > cat("Matrix A:\n") Matrix A: > print(A)      [,1] [,2] [1,]    2    1 [2,]    0    3 > cat("\nMatrix B:\n") Matrix B: > print(B)      [,1] [,2] [1,]   ...

Generic Functions in R

What I Did   This assignment helped me learn how R's generic functions work and the difference between S3 and S4 objects. I used the mtcars dataset to see how functions change behavior based on what kind of object they're working with.   Loading the Dataset   First, I loaded mtcars data(" mtcars ") head( mtcars ) str( mtcars )   This dataset has 11 columns with things like miles per gallon, horsepower, Etc . How Generic Functions Work   I tested some basic R functions to see how they adapt to different objects:   summary( mtcars ) plot( mtcars )   lm_model = lm (mpg ~ wt + hp, data = mtcars ) summary( lm_model )   What I noticed: when you run summary( ) on a data frame, you get min/max/mean values. But when you run it on a linear model, you get totally different outputs, like coefficients and p-values. Same function name, different behavior!   Creating S3 Objects   S3 is the simpler object system. Here's how I made one:   s3...
