Welcome!
Welcome to my blog! A brief introduction to me is on the About page – head over there now before reading on! So I’ve been a Data Scientist for about 6 months now and already I feel like I’ve been on quite a journey. Below is a summary of some of the things I’ve been doing, some of the choices I’ve made, and where I want to go next. Wher...

RStudio + Blogdown + Github + Netlify = A winning formula
I thought it was worth posting about how I set up this blog as I had enormous trouble setting it up. I’d never done anything like this before and so some Google searching exposed me to many different technologies, but I had no clue what they did, which were best/easiest to work with and which combination I needed to use them in. First off, big ...

Star Wars: Galaxy of Heroes – who knew a mobile game could be so complicated?!
How I started playing What are mods?? Laying the groundwork Reading in game data Cleaning it up Let the shenanigans begin!! Attempt 2: Brute force… The eventual resignation… How I started playing Back in 2015, during the boring period between Christmas and New Year, I decided to try out a Star Wars mobile game. Star Wars: Galaxy of Heroes is...

Sometimes learning is not fun
Happy New Year! I’ve spent the time between Christmas and New Year being more productive than I would usually be, trying things out in R, some (relatively) successfully, others…not so much. I thought it would be worth writing about how embarking on Data Science isn’t all plain sailing, and can at times be incredibly frustrating! You often s...

If at first you don’t succeed…
After having some time to ponder the issues I was having in my last post, I’m pleased to say that all three are resolved, or at least partially to my immediate satisfaction. First off, I managed to get Netlify to automatically build my website for me, thanks to the helpful advice of their online support team. It turns out I was making a very si...

Embarking on nested dataframes
In a recent sprint, I was faced with the problem of carrying out analysis on data extracted from a database where there were several instances of the same table type and I wanted to do the same tasks on each of them. I know enough about the tidyverse to realise that this was a good opportunity to use functions such as map() and nest(). However, I...

Learning some tough lessons!
It’s been a while since I’ve posted – mainly because I got myself into a mess with Git and I’ve been putting off trying to sort it out. I’ve been wanting to post about htmlwidgets for a while now, and in my naivity I thought I’d retrospectively try to use the DT package on one of my older posts to jazz up the tables to be more interac...

Portsmouth R User Group – 2nd Meeting
Last month I attended my first ever R User Group meeting, which was held at the University of Portsmouth in their impressive Future Technology Centre. I’d been itching to go to one of these meetups for a while, but unfortunately there was nothing in the South of England, so when this opportunity came around I couldn’t miss it, especially as I...

Two years in Data Science and not yet a Data Scientist
What’s in a name? Despite the potentially grumpy sounding title of this post, this is more a positive reflection of the past two years since I started working in Data Science. I think I’ve come a long way, but there is still so far to to go if I am to confidently call myself a Data Scientist. Why does a job title matter? It’s a good way of ...

Mapping homelessness in England
Introduction Data wrangling Initial analysis The painful part Introduction For this blog post, I decided to try to find a dataset covering an issue I feel quite strongly about – homelessness. I managed to find a fairly large dataset from the Cambridgeshire Insight website. For a while I’ve wanted to try out R’s mapping potential and hopefu...
