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 ...

Introduction Often when scraping data, websites will ask a user to enter a postal code to get the locations near it. If you are interested in collecting data on locations in Canada for an entire Province or the entire province from a site, it might be hard to find a ...

Candlestick plots are something you see regularly when dealing with stocks. Whether you are an investor, an analyst or even an outsider, this type of chart always in interesting to look at. In this brief blog, I’m going to share a custom function I made for making a candlestick ...

Introduction As surprising as it may sound, many new R programmers are unaware of Base R syntax and the powerful functions that come with it- many of which do what functions from packages like dplyr and the rest of the tidyverse do. In this short blog post I am going ...
