R Programming Examples
Summary
The purpose of this page is to display some of my projects/examples of previous work using R. All of these files are uploaded to my Github Repository (Portfolio-Projects).
Modeling with R Using Airline Data
This model was created as part of my completion of the IBM Data Analysis with Excel and R Professional Certificate. I used the tidyverse library to create linear and polynomial models to run predictive statistics on airline data. The metrics used to evaluate each model include their coefficients, mean squared error, mean absolute error, and R^2 error. The source code is linked below.
Model Evaluation using Airline Data
This model was created as part of my completion of the IBM Data Analysis with Excel and R Professional Certificate. I used the tidymodels, glmnet, and rlang libraries to create models and use training/testing data to analyze airline data. The training set was used to train the model, which was evaluated using the testing set. The source code is linked below.
SQL for Data Science with R
This analysis was a part of my completion of the IBM Data Analysis with Excel and R Professional Certificate. I imported the RSQLite library to run SQL queries within my R code. The source code is linked below.
Visualization with R using Airline Data
This visualization was created as part of my completion of the IBM Data Analysis with Excel and R Professional Certificate. I used the tidyverse and corrplot libraries to visualize airline data. Descriptive statistics include count, mean, standard deviation, minimum, maximum, IQR, and median. The source code is linked below.
