Where to Live in Barcelona in a Dashboard

Barcelona best barrio visualization

Sometimes data can tell a story much faster and effectively than many words. That's why I´ve decided to start sharing more data stories via this blog, hoping to both:

  1. address specific topics readers want to dive in (often these will not be data-people, they would be new to my blog, probably coming after googling a specific questions e.g. "which are the best boroughs to live in Barcelona?").
  2. showcase data visualization tools and best practices to present your data (these are data-people, yes you my regular readers, you might like to see a tool in action).

Scheduling R Markdown Reports via Email

GA markdown report using R
R Markdown is an amazing tool that allows you to blend bits of R code with ordinary text and produce well-formatted data analysis reports very quickly. You can export the final report in many formats like HTML, pdf or MS Words which makes it easy to share with others. And of course, you can modify or update it with fresh data very easily.

I have recently been using it R Markdown for pulling data from various data source such Google Analytics API and MySQL database, perform several operations on it (merging for example) and present the outputs with tables, visualizations and insights (text).

But what about automating the whole report generation and emailing the final report as an attached document every month at a specific time?
