Ok … welcome back to this covid19 data analysis series with R. In this series, we’re analyzing covid19 data with the R programming language. So far in this series, we’ve done several things: We retrieved a simple covid19 csv file in part 1 In part 2, we created a process to retrieve several related covid19 … Read more
Welcome back. Hopefully you’ve been following along with our R data analysis series. This tutorial is part of a series of tutorials analyzing covid-19 data with R. So far in this series, we’ve used R to retrieve a simple covid19 dataset. Later, we used R to create a repeatable process for data retrieval and cleaning. … Read more
This tutorial will show you how to add ggplot titles to data visualizations in R. It will show you step by step how to add titles to your ggplot2 plots. We’ll talk about how to: add an overall plot title to a ggplot plot add a subtitle in ggplot change the x and y axis … Read more
This tutorial will show you how to use facet_grid in ggplot2. Specifically, it will show you how to use facet_grid to create small multiple charts. facet_grid is fairly easy to understand, but it assumes some basic knowledge of ggplot2. ggplot2 is a data visualization package for the R programming language. If you don’t already know … Read more
This blog post is a fairly comprehensive ggplot2 tutorial for beginners. If you’re new to R and ggplot, this ggplot2 tutorial will cover a few things: What ggplot2 is The syntax of ggplot2 Examples of how to use ggplot2 If you’re new to ggplot, I recommend that you read the whole tutorial. But if you … Read more
This tutorial will teach you how to use facet_wrap to create small multiple charts in ggplot2. The small multiple design is an incredibly powerful (and underused) data visualization technique. facet_wrap is great, because it enables you to create small multiple charts easily and effectively. It makes it easy to create small multiple charts. Having said … Read more
This tutorial will show you how to use geom_line to create line charts with ggplot2. Using geom_line is fairly straight forward if you know ggplot2. But if you’re a relative beginner to ggplot, it can be a little intimidating. That being said, I’m going to walk you through the syntax step by step. We’ll first … Read more
One of the most important skills you’ll need as a data scientist (and a junior data scientist in particular) is telling stories with data. Companies, hiring managers, and recruiters not only need you to be able to find insights in data; they also need you to be able to communicate with data. In practice, communicating … Read more
For many data scientists and data analytics professionals, as much as 80% of their work is data wrangling and exploratory data analysis. Of course, everyone wants to focus on machine learning and advanced techniques, but the reality is that a lot of the work of many data scientists is a little more mundane. That isn’t … Read more
This week, here’s another map: a map of world oil production that you can create using R.
As I’ve mentioned, projects like this – a few hundred lines of code, with a variety of functions from the tidyverse – are excellent practice for intermediate data scientists.
