Installation Report:

I began by downloading the latest version of R according to my operating system. After the R installation completed, I proceeded to download RStudio Desktop. Both installers were straightforward, making sure to select the correct version for my system. Once installed, I opened RStudio to confirm that it recognized R properly. The console displayed the version information successfully, and I captured a screenshot of the console window as required, as seen above.

During the installation, I did not encounter any major issues. The only minor challenge was ensuring that my operating system’s security settings allowed the installer to run, on macOS. Once I approved it, the installation proceeded without further problems. My system is running macOS Ventura 13.5, with R version 4.4.2 installed. I am using RStudio version 2024.12.0+467, which provides the interface for working with R.

An R vector is a one-dimensional structure that stores elements of the same data type, such as numeric values, characters, or logical values. Vectors are essential in R because they serve as the foundation for nearly all data structures and operations within the language. Much of R’s power comes from its ability to apply functions and calculations across entire vectors at once, rather than requiring explicit loops. This vectorized approach makes data analysis more efficient, both in terms of computation and readability of code. Because of this, understanding vectors is critical for working effectively with data in R, as they underpin everything from basic calculations to more advanced statistical and data science workflows.

Module 2. Assignment: Function Debugging and Evaluation in R

Image
 Assignment Instructions: The initial test results can be found below and included the following error message: "Error in myMean(assignment2) : object 'assignment' not found".  The reason why this function failed is because assignment and someData are undefined variable names. R cannot identify their function and they are not existing objects in the environment, and as a result produces an error message.  Now, a corrected version of myMean that correctly returns the mean of assignment2 will be computed.  The mean is  19.07692. In this iteration, we changed the parameters to include 'data' and both sum(data) and length(data) use the same parameter. Consistent variable names are important in R programming to ensure data integrity and cohesion!

Module 8. Assignment CSV files

Image
  (please click images for higher clarity) The images above showcase file‑write operations succeeded and the R code.  The first step imports the data without commas, from the dataset.txt file. It then creates a summarized table that shows the average grade for males and females. The resulting data frame, gender_mean, is then written to a tab-delimited text file named gender_mean.txt for reference or sharing. The second step filters the data to find all students whose names contain the letter “i” or “I,” using the grepl() function. A smaller data frame, i_students, is created from these matching rows and saved to a csv file. The final step produces a new csv file, created including all original columns, for just the names including the letter "I". This is the final document for this project, creating a new data set containing just those names.
