Welcome to my site.

I’m an NHS data analyst / BI developer based in Scotland.

This blog is mainly about R - an open source statistical programming language.

Why R?

Because I like it, there is a lot to learn, and there are plenty of SQL and Excel blogs out there already. Occasionally I write about other tools, and might pivot to new things in the future. But R is what I find myself wanting to use in my spare time.

Why should I listen to you?

Because I’ll help you learn.
Mainly R, but also SQL, Excel, Statistical Process Control, BI…

I know what it is to struggle to understand something, and how good it feels when you finally get it, and can move on with your work.

I am always delighted to hear that my posts are helping others.

I am told that I’m good at simplifying and explaining things - I think that is a useful quality.

I am self taught - I don’t have a background in computing or statistics, so if I can do this, you can too.
