  • What is an R vector? Why vectors are fundamental to data analysis in R?


An R vector is basically a list of values in R that are all the same type, like a group of numbers, words, or true/false values. Vectors are really important in R because almost everything you work with is built from them, including data frame columns and the results of calculations. Since R is designed to work with vectors all at once instead of one value at a time, it makes analyzing data faster, easier, and less complicated.

  • Any issues you encountered during R and RStudio installation? 

During the installation process, I ran into a few minor issues but nothing too serious. The main problem was that R installed correctly, but RStudio wouldn’t recognize the R version at first. When I tried to open RStudio, it gave an error saying it couldn’t find R on my system. This was a little confusing at first because I was sure R had already been installed.

To fix the issue, I double-checked the installation order and realized that R needs to be installed before RStudio. I uninstalled RStudio, reinstalled the latest version of R, and then reinstalled RStudio afterward. Once I did that, everything worked as expected. I also restarted my computer just to be safe, which helped ensure the programs were properly linked.

I am running this setup on Windows 11 (64-bit). My R version is 4.3.2, and my RStudio version is 2023.12.1+402. After resolving the installation issue, both R and RStudio are running smoothly, and I haven’t had any additional problems so far.

Assignment #10: Building Your Own R Package

 # Proposal for My R Package: Friedman For this project, I am proposing an R package called **Friedman**. The purpose of this package is to provide beginner-friendly tools for simple data analysis and visualization in R. Many students and new R users struggle with repetitive tasks such as cleaning datasets, calculating summary statistics, and creating clear visualizations. This package will help make those tasks easier by grouping useful functions into one simple package. The main audience for this package is students, beginner analysts, and anyone who wants a more straightforward way to explore data in R. Instead of writing long code repeatedly, users will be able to call functions from Friedman to quickly summarize and visualize their data. This makes the package especially useful for class assignments, small research projects, and practice with R programming. Some of the key functions I plan to implement include: - `clean_data()` – removes missing values or standardizes column n...
