Introduction Recently I discovered stackshare.io’s stackups which offers comparisons of different programming languages as well as their pros and cons. While looking at the all too classic comparison available between R and Python I noticed that one of the cons listed was: Messy syntax for string concatenation While ...

Introduction Geo-spatial analysis and visualizations is a powerful tool for providing insight bringing an idea or a result in a more tangible manner. Oftentimes, we are only interested in a specific points or we wan to classify the data we have by a larger location it belongs to. In this ...

Disclaimer: This was originally written on my Medium blog here, so the formatting is a little different from my usual style. I have been blogging for nearly two years and with it I got to learn a lot about writing good code, challenges that arise (particularly with data science) and ...

Introduction Recently, a friend running a non-profit reached out to me for some help with transforming his data. He ran a raffle campaign where he sold tickets to donors and wanted to turn the record of ticket sales into a record of raffle entries. The problem usually would take the ...

Introduction Recently, I have started taking a course on Bayesian statistics and using Stan– a fast language designed specifically for preforming the simulations necessary for Bayesian analysis by employing Markov-Chain Monte Carlo (MCMC) algorithms. While it may sound abstract, thousands of users rely on Stan for statistical modeling, data analysis, ...

Introduction I have clearly been out of the loop because I have only recently learned about the tesseract library in R. If I knew about it earlier I would have wrote about it much sooner! The tesseract library is a package which has bindings to the Tesseract-OCR engine: a powerful ...

Introduction With the R6 library enabling users to create object classes, it is possible to solve a variety of computer science problems using R. Following the same fashion of my previous blogs on tree search algorithms (see here, here, here and here), in this blog I explore solving linked list ...

Introduction With my recent breakthrough in figuring out how OOP works in R by using R6 classes, a whole new world of possibilities is open to explore with it. While R is defined by Wikipedia) as “[…] a programming language for statistical computing and graphics” R6 classes allow for applications of ...

Introduction In my previous blogs, I introduced how to preform depth-first and breadth-first searches in R with R6 objects. After knowing how to do this I explored solving tree-includes problems with both of these searches. In this blog I am going to share how to solve binary “tree sum” problems ...

Introduction Following the same style of my previous blogs on binary search. In this blog I present how solve “tree includes” problems in R with R6 objects. The solutions and the code is based on my translation of Alvin the Programmer’s javascript code into R from his video on ...

Introduction In my last blog I shared how to do a depth-first search in R by using R6 classes. In this short blog I’m going to show how to do a breadth-first search. Breadth-first search: A brief explination. In contrast to a depth-first search which traverses a tree by ...

Introduction The more I use R, the more I am convinced that you can do anything with it. Recently, I checked out FreeCodeCamp’s video “Binary Tree Algothritms for Technical Interviews” and was told that I can write the code in any language I want. While Alvin used Javascript, I ...

Introduction While I thought I would to put exploring making maps in leaflet to rest, I was tempted to touch making flight maps similar to the ones on Atlas.co and have successfully managed to do it by incorporating the geosphere package. In this blog I am going to share ...

Introduction Using Mapbox is a wonderful way to create beautiful maps with leaflet. In my last blog, I spoke about reverse engineering Atlas.co and how to create maps that are similar to the maps produced there. After a bit of Googling I was lead to this post where I ...

Introduction A while back, the famous travel Youtubers Kara and Nate announced that they launched a new company called Atlas.co which prints custom souvenir maps as hangable artwork. After spending some time looking at how the maps looked I thought it would be interesting to see if it is ...

Introduction Over the past while with my time on LinkedIn, I got to have exposure to many people from many different lines of work. I also managed to have carved a space for myself there where I can post about Data Science topics and share my blogs along the way. ...

Introduction “There is no unique definition of a square root of a matrix. While there are a few ways to calculate it in closed form, the results differ”. It was from these notes that I read in my multivariate statistics class that inspired me to explore the the geometric interpretations ...
