Comparing Base R, Lattice, and ggplot2

I used the Guns dataset to explore how concealed carry laws relate to crime rates across US states from 1977-1999.

Syntax Differences

Base R uses simple commands like plot() and boxplot() but requires multiple steps to customize visualizations. Lattice introduced a formula syntax that made creating panel plots much easier, especially with the | operator for conditioning. ggplot2 uses layered grammar with + to build plots, which felt more logical once I got used to it.

Which System Works Best

ggplot2 produced the cleanest output with less code. The default styling looked professional and adding features like smoothing lines was straightforward. Lattice worked well for conditioned plots but felt limited outside that use case. Base R gave me direct control but required more manual work for decent results.

Challenges

Switching between systems was harder than expected. Each has different logic for the same task. ggplot2's faceting with facet_wrap() was surprisingly simple compared to achieving the same thing in base R. The biggest lesson was that ggplot2 saves time when you need publication-ready graphics, while base R works fine for quick exploratory plots.

  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 ...

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...
