In this post I’ll show you how I logged my phone use with tasker, in a follow up post I’ll show you how I visualized that.
I had a great vacation last week but relaxing in Spain I thought about my use of technology and became a bit concerned with how many times I actually look at my phone.
But how many times a day do I actually look at my phone?

In this post I will show you how to run an R script on heroku every day. This is a continuation of my previous post on tweeting a death from wikidata.
Update 2022: heroku is no longer offering free options.
Why would I want to run a script on heroku? It is extremely simple, you don’t need to spin up a machine in the cloud on AWS, Google, Azure or Nerdalize.

In this explainer I walk you through the steps I took to create a twitter bot that tweets daily about people who died on that date.
I created a script that queries wikidata, takes that information and creates a sentence. That sentence is then tweeted.
For example:
A tweet I literally just send out from the docker container
I hope you are has excited as I am about this project.

TL;DR:
In this post I will show you how to set up special header information on a static website such as hugo + netlify. Netlify interprets the _headers file and applies the rules to your website. You only have to set a simple rule, and now you too can keep Terry Pratchett alive!
GNU Terry Pratchett On March 12th 2015 one of my favorite writers; Terry Pratchett died, but the people of the internet were not ready to let him go.

It is my dream to do everything with R. And we aRe almost there. We can write blogs in blogdown or bookdown, write reports in RMarkdown (thank you Yihui Xie!) create interactive webpages with Shiny (thank you Winston Chang). Control our lifx lights with lifxr (great work Carl!) and use emoticons everywhere with the emo package.
There is even a novel of my vision! I recently found chapter 40 of A Dr.

Intro and setup This is a simple explanation of how to write a manuscript in RStudio. Writing a manuscript in RStudio is not ideal, but it has gotten better over time. It is now relatively easy to add citations to documents in RStudio.
**The goal is not think about formatting, and citations, but to write the manuscript and add citations on the fly with a nice visual help. **
This tutorial explains how to link Zotero (a reference manager) to your project folder and how to easily add citations.

Introduction Last week I was playing with creating maps using R and GGPLOT2. As I was learning I realized information about creating maps in ggplot is scattered over the internet. So here I combine all that knowledge. So if something is absolutely wrong/ ridiculous / stupid / slightly off or not clear, contact me or open an issue on the github page.
When you search for plotting examples you will often encounter the packages maps and mapdata.

It often makes sense to separate your projects. And since space is cheap you are probably creating separate folders on your computer. In RStudio you can create different projects that live in their own folder.
When you start a different project the files of that project work independently from other projects. And the standard locations of your workspace and other things are also separated from the rest.
In my case, for example, I have several projects and the last 10 or so are displayed in the dropdown menu:

This is the second part of working with ggplot. We will combine the packages dplyr and ggplot to improve our workflow. When you make a visualisation you often experiment with different versions of your plot. Our workflow will be dynamic, in stead of saving every version of the plot you created, we will recreate the plot untill it looks the way you want it.
In the previous lesson we worked with some build in datasets.
