I’m an NHS data analyst based in Inverness, Scotland.
I don’t think “data analyst” accurately conveys what I do on a daily basis, Hence, you’ll find me on Twitter as @HighlandDataSci.
I don’t feel entirely comfortable with the term “data scientist” - but I do a lot of importing/merging & cleaning of data sets, writing code, data visualisation, and explaining results to others. In short - I’m getting there!
I began using R for data visualisation, and, over time, it has become integral to my workflow. It’s just so flexible, and the more you get immersed in the R world, the more you realise what you can do with it.
I’m also getting to grips with data.table, which is both fast and reduces the amount of code I need to write.
I’ve also used R for:
I’m also interested in using R for time series (using forecast) and predictive analytics.
In addition to R, and driven by the large scale data requirements of my role, I’ve also developed skills in:
- SQL, including complex T-SQL queries and SQL Server Integration Services (SSIS)
- Exensive experience of using data for improvement, particularly Run Charts and Statistical Process Control
- SQL Server Reporting Services
- Excel Dashboards / Advanced Excel
- VBA, including custom functions and manipulating other MS Office software from within Excel
About this blog:
This is a forum for me to show some R work:
- Anything I produce for demonstration at our local R user group (InveRness RUG)
- Notes to myself on things I’ve learned (the hard way) at work
- Chart makeovers using R
- Exploring techniques and technology that I don’t currently use in my role
Most of the code I write will appear on my github as a gist or repository.
My code is pretty well commented, so I don’t go into too much depth in these posts.
Some posts will be related to things I am learning about for my own development, so they may not go into a lot of detail but I aim to update these as my learning increases.
Please check the session info on the code scripts for details of loaded packages and dependencies.
My R skills are not at the level of the awesome Hadley et al, at least, not yet.
It does bug me when I see an interesting blog post and find that the code does not work when you try to use it.
I am confident that if you run my code as is it will work. There may be a slicker way of doing things, but there will be an end result.
At the moment I’m not posting as frequently as I would like - the challenge of work and a young family.
I’ve disabled comments / disqus on the site because of their effect on page load times. However please do get in touch if you have any comments.
