Got my Raspberry Pi 4

The Raspberry Pi 4 is in short supply here in Australia (and the world for that matter), especially the 4gb version which is what I purchased.

Raspberry Pi Zero W (Wireless) and Raspberry Pi 4 Model B 4GB with official cases

I received the 4gb SKU of the Pi 4B, the offical case and a USB-C to micro USB adapter so I could plug my old power supply in.

The new USB-C power supply is on back order until August 2019

Started studying a book I purchased in February Data Visualization: A Practical Introduction

The book provides students and researchers a hands-on introduction to the principles and practice of data visualization. It explains what makes some graphs succeed while others fail, how to make high-quality figures from data using powerful and reproducible methods, and how to think about data visualization in an honest and effective way.

 Data Visualization builds the reader’s expertise in ggplot2, a versatile visualization library for the R programming language. Through a series of worked examples, this accessible primer then demonstrates how to create plots piece by piece, beginning with summaries of single variables and moving on to more complex graphics. Topics include plotting continuous and categorical variables; layering information on graphics; producing effective “small multiple plots; grouping, summarizing, and transforming data for plotting; creating maps; working with the output of statistical models; and refining plots to make them more comprehensible.
