Feed: R-bloggers. Author: Tim Bock. Infographics, dashboards, and reports often need to highlight or visualize a single number. But how do you highlight a single number so that it has an impact and looks good? It can be a big challenge to make a lonely, single number look great. In this post, I show 12 different ways of representing a single number. Most of these visualizations have been created automatically using R. When to create a visualization to represent a single number There are a number of situations in which it can be advantageous to create a visualization to represent ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Jean-Cyril Schutterle. Even just five years back, Artificial Intelligence (AI) was still the stuff of science fiction, confined to research labs and tech giants’ showcases. It was pretty similar to the auto show concept car – there to be admired but not to be touched. Today, though, AI is everywhere. Whether it’s virtual assistants scheduling our meetings, facial recognition software or increasingly autonomous cars, AI is making itself felt in all our private and professional lives. One thing is certain – AI is here to stay. But quite what its impact ... Read More

Feed: Big Data Made Simple - One source. Many perspectives.. Author: Manu Jeevan. Data science has gathered a lot of steam in the past few years, and most companies now acknowledge the integral role data plays in driving business decisions. Python, along with R, is one of the most handy tools in a data scientist’s arsenal. It’s also one of the simplest computer languages to learn and use, primarily because most concepts can be expressed in fewer lines of code in Python, than in other languages. Hence, beginners venturing out into the field of data science should definitely familiarise themselves ... Read More

Feed: Planet big data. Author: Ronald van Loon. “Data will talk to you if you’re willing to listen”— Jim Bergeson. Few can dispute that. However, the challenge comes when data transforms into bundles and stacks of unorganized and unstructured data sets. The challenge comes with listening to big data and making sense of what it says. With big data, the conversing data becomes loud and noisy. You don’t hear the voice; you hear the cacophony. This is where organizations struggle. And, amidst a struggle, you look up to the leaders to see how they are rising to the challenge. You ... Read More

Feed: R-bloggers. Author: hrbrmstr. International Code Talk Like A Pirate Day almost slipped by without me noticing (September has been a crazy busy month), but it popped up in the calendar notifications today and I was glad that I had prepped the meat of a post a few weeks back. There will be no ‘rrrrrr’ abuse in this post, I’m afraid, but there will be plenty of R code. We’re going to combine pirate day with “pirating” data, in the sense that I’m going to show one way on how to use the web scraping powers of R responsibly to ... Read More

Feed: Planet PostgreSQL. Oh my goodness, Data Days! When we rescheduled PGConf US Local: Seattle from August to November we did so due to attendee feedback. It was amazing - people didn't want to go to a conference on Saturday in August (I wonder why). I know, we should have known but it was a new model and we tried. We are extremely pleased with the results of the shift in schedule. The conference now takes place during "professional hours" on "professional days." Because of the shift and sponsor support we have added three new tracks, reopened the CFP, and ... Read More

Feed: R-bloggers. Author: Shirin's playgRound. I have written a blog post about why I love R and prefer it to other languages. The post is on my new site, but since it isn’t on R-bloggers yet I am also posting the link here: Working in Data Science, I often feel like I have to justify using R over Python. And while I do use Python for running scripts in production, I am much more comfortable with the R environment. Basically, whenever I can, I use R for prototyping, testing, visualizing and teaching. But because personal gut-feeling preference isn’t a very ... Read More

Feed: R-bloggers. Author: Sharp Sight. Last week’s blog post about Amazon’s search for a location for a second headquarters left me thinking about the company’s growth. After looking at the long term growth of the stock price, it occurred to me that visualizing the stock price data would be a great example of how to create a line chart in R using ggplot2. So in this blog post, I’ll show you how to make a line chart with ggplot2, step by step. Let’s jump in. First, we’ll load several packages: we’ll load readr, which we’ll use to read in the ...
