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 ...

Visualizing Global Climate Change

Introduction     For this assignment, I used an AI tool called Claude to generate a visualization titled "Global Climate  Crisis Dashboard. This dashboard displays critical environmental indicators tracking Earth's changing climate from 1990 to 2023. It highlights key trends such as rising temperatures, sea levels, atmospheric CO₂, and Arctic sea ice loss. View the visualization below:   file:///Users/user/Downloads/climate_viz_html.html   Description of the Visualization:   The dashboard provides an overview of several vital climate indicators:   Global Temperature: Since 1990, Earth's average temperature has increased by +1.05°C, with the most rapid warming occurring in the last two decades. This trend approaches the critical 1.5°C limit warned by scientists.   Sea Level Rise: Ocean levels have risen by 27.1 mm over 33 years, threatening millions of coastal residents worldwide. The rate of rise is accelerating due to thermal expansion and ice ...
