5. Genetic Analysis Using Network Plots
This R project is for those who intend to learn R for biological applications and would like to practice data visualization techniques.
A common way for genetic biological data to be analyzed is to generate a network plot of related genes. This will represent a gene network.
You’ll have to use data-wrangling techniques to prepare the datasets for visualization. This preprocessing step would help you learn basic data exploration of complex and large biological datasets.
Next, using packages such as Cytoscape, ggnet2, and igraph, you can generate network plots in R from RNAseq microarray data.
6. Social Network Analysis
In a similar network analysis to gene data, you can also work on a machine learning project in R focusing on social networks.
In this project, you’ll learn to collect data from the web (Twitter, Facebook etc) and use visualizations to understand the relationships between people online.
You’ll also practice data-cleaning techniques in R to prepare datasets for network analysis. Dplyr is a good package to help clean up all the messy data.
Packages such as igraph, ggnetwork, and networkd3 can help you generate great visualizations of social networks.
7. Technical Content Creation
Next, to showcase your knowledge of R programming, you can work on something else unlike all the other programming projects—creating technical content.
Having some technical content to support your code is a great addition to your portfolio.
Write up a few tutorials explaining the basics of R and some more complex concepts such as building machine learning models in R.
Some common platforms to present your R code include:
8. R Shiny App for Movie Recommendation
When working on data science projects in R, you should also consider creating an R shiny app.
An R shiny app is an interactive application built entirely using R code. The app allows users to interact with your code using an easy to use graphical user interface.
For example, you could create an app that provides movie recommendations based on the user’s preferences.
The idea is to use different packages on the backend for data wrangling and machine learning algorithms such as ggplot2 and caret in R.
The end result should be a front-end interface hosted on the web that you can use and show off on your portfolio!
9. Customer Segmentation Using Clustering in R
If you’re interested in learning clustering in R, do consider a customer segmentation project too.
This project involves using unsupervised learning techniques such as K-means clustering on customer data sets.
You’ll learn to apply basic exploratory data analysis (EDA) techniques in R to gain insights into the data set. Then you’ll need to wrangle and clean up the data before running it through a K-means clustering machine learning algorithm.
Using packages such as ggplot2, FactoMineR, and cluster will help you generate neat visualizations of the customer segments.
You might also want to explore other machine learning methods to do customer segmentation such as hierarchical clustering if it applies.
10. Weather and Climate Change Forecast
The next project on this list is for those who are interested in learning about how climate change is measured through data.
By using freely available data from the World Climate Database, you can extract and explore historical weather trends over the years.
Use packages such as dplyr to wrangle and clean up the datasets. Then use ggplot2 to create some data visualizations of weather and climate trends.
If you’re feeling adventurous, you can even attempt to build a machine learning model in R to do climate change forecasting for the future.
You’ll need to explore and experiment with different supervised learning algorithms such as Random Forest and Linear Regression to get the best results.
11. Churn Prediction using Logistic Regression
Churn prediction is a common problem in data science that involves predicting whether a customer will stay with the company or unsubscribe from its services.
Based on my experience, most data scientists working in large businesses would have encountered a churn prediction project somewhere in their careers.
You can use existing customer data to create a churn prediction model using logistic regression in R.
Start by doing exploratory data analysis (EDA) on the dataset and then wrangling and cleaning up the data for statistical analysis and modeling.
Then use logistic regression to train a model on the dataset and make churn predictions on unseen customer data. You can also explore other machine learning methods such as decision trees or random forests if it applies.
Packages like caret can help with running your machine-learning models. You can use ggplot2 to help you visualize your results as well.
