Feed: R-bloggers. Author: Tim Bock. Infographics, dashboards, and reports often need to highlight or visualize a single number.

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: 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 ...

Feed: R-bloggers. Author: Troy Walters. Many of the methods used in time series analysis and forecasting have been around for quite some time but have taken a back seat to machine learning techniques in recent years. Nevertheless, time series analysis and forecasting are useful tools in any data scientist’s toolkit. Some recent time series-based competitions have recently appeared on kaggle, such as one hosted by Wikipedia where competitors are asked to forecast web traffic to various pages of the site. As an economist, I have been working with time series data for many years; however, I was largely unfamiliar with ... Read More

Feed: R-bloggers. Author: Jonathan Sidi's R Blog. Take the mystery out of CRAN level package maintenance – Thinking of creating a new package? Dread the task of function documentation? Afraid to run devtools::check(build_args = '--as-cran') and get bombarded by Errors, Warnings, and Notes (oh my!) ? Wait…. breathe! After feeling all that anxiety and following all of Hadley’s directions online, I felt I was doing a lot of manual labour, and that a package should be doing all lot of this for me. So we wrote one – sinew (sin-yu). tl;dr: sinew is an automatic roxygen2 documentation creator Quick example, ... Read More

Feed: R-bloggers. Author: Chris Baker. Why care about patents? 1. Patents play a critical role in incentivizing innovation, withoutwhich we wouldn't have much of the technology we rely on everyday What does your iPhone, Google's PageRank algorithm, and a buttersubstitute called Smart Balance all have in common? …They all probably wouldn't be here if not for patents. A patentprovides its owner with the ability to make money off of something thatthey invented, without having to worry about someone else copying theirtechnology. Think Apple would spend millions of dollars developing theiPhone if Samsung could just come along and rip itoff?Probably not ... Read More

Feed: R-bloggers. Author: business-science.io - Articles. Employee turnvover (attrition) is a major cost to an organization, and predicting turnover is at the forefront of needs of Human Resources (HR) in many organizations. Until now the mainstream approach has been to use logistic regression or survival curves to model employee attrition. However, with advancements in machine learning (ML), we can now get both better predictive performance and better explanations of what critical features are linked to employee attrition. In this post, we’ll use two cutting edge techniques. First, we’ll use the h2o package’s new FREE automatic machine learning algorithm, h2o.automl(), to ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A brandnew and very exciting (to us, at least) package called pinp just arrived on CRAN, following a somewhat unnecessarily long passage out of incoming. It is based on the PNAS LaTeX Style offered by the Proceeding of the National Academy of Sciences of the United States of America, or PNAS for short. And there is already a Markdown version in the wonderful rticles packages. But James Balamuta and I thought we could do one better when we were looking to typeset our recent PeerJ Prepint as an attractive looking vignette for use ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A new version of drat arrived earlier today on CRAN as another no-human-can-delay-this automatic upgrade directly from the CRAN prechecks. It is mostly a maintenance release ensuring PACKAGES.rds is also updated, plus some minor other edits. drat stands for drat R Archive Template, and helps with easy-to-create and easy-to-use repositories for R packages. Since its inception in early 2015 it has found reasonably widespread adoption among R users because repositories with marked releases is the better way to distribute code. The NEWS file summarises the release as follows: Changes in drat version 0.1.3 ... Read More
