FiveThirtyEight’s Riddler Express link Riddler City is a large circular metropolis, with countless square city blocks that each have a side length of 1 km. A small section of the city, composed of 36 blocks, is shown in the diagram below: At the very center of the city lies Riddler City Hall. Its many employees all walk to and from work, and their homes are...
Every Tuesday, the R4DataScience community posts a dataset online as part of #TidyTuesday as practice wrangling and modelling data. For the week of 5th May 2020, the dataset concerned the video game Animal Crossing. Intro Radiohead - How I Made My Millions I don’t play Animal Crossing (unfortunately Nintendo Switches sold out as the UK went into lockdown), but it seems that...
easyalluvial allows you to build exploratory and interactive alluvial plots (sankey diagrams) with a single line of code while automatically binning numerical variables. This release 0.2.3 ensures dplyr 1.0.0 compatibilitiy and now builds a slick pkgdown documentation website and makes better use of Travis CI using multiple builds to test compatibility with development versions of selected package dependencies. New ‘pkgdown’...
Amidst controversy in several (perhaps many?) countries about the timing and pace of opening up from COVID-19 control measures, one small corner of the argument today related to why Texas is seeing record numbers of new cases of COVID-19 in the days after a range of opening up measures. In a thread on Twitter, @SeanTrende argued that the worrying...
I caught this tweet by Terence Eden about using Twitter image alt-text to “PGP sign” tweet and my mind immediately went to “how can I abuse this for covert communications, malicious command-and-control, and embedding R code in tweets?”. When you paste or upload an image to tweet (web interface, at least) you have an opportunity... Continue reading →
Files A comma-separated values (CSV) file is a delimited text file that generally uses a comma to separate values. A CSV file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by the delimiter. CSV is a common data exchange format that...

The ‘parallel’ package Reference: https://bookdown.org/rdpeng/rprogdatascience/parallel-computation.html Many computations in R can be made faster by the use of parallel computation. Generally, parallel computation is the simultaneous execution of different pieces of a larger computation across multiple computing processors or cores. The parallel package can be used to send tasks (encoded as function calls) to each of the processing cores on your machine in parallel. The...

I’ve spoiled it by putting the gif at the start of the post but if you are interested in how it was made then read on! I’ve seen this kind of charts around the web so I wanted to make a tennis-related one and what better than using Grand Slam wins since the very beginning; 1877. The main package that is...
Yesterday, along with R-Ladies Founder Gabriela de Queiroz I was honored to be asked to give a short talk at an online graduation ceremony for the BSc and MSc Statistics Graduates of the class of 2020 (all R users) at the California State University, East Bay. My talk contains some statistics jargon, but I thought it might be helpful...

R package vignettes are user-friendly ways to demo your package's capabilities. They can also be helpful documentation for your own reference when modifying the package in the future -- "what was I thinking there?" The easiest way to create a vignette in RStudio is using File | New File | R Markdown | From Template | Package Vignette (HTML). Write your...

After having successfully run a simple R-script inside a Docker container before, we next attempt to repeat this process for entire apps built within the RShiny framework. Join me on the next step toward deploying your work done in R with the help of neat Docker containers! Der Beitrag How To Dockerize ShinyApps erschien zuerst auf STATWORX.

The 2 most popular data science languages - Python and R - are often pitted as rivals. This couldn’t be further from the truth. Data scientists that learn to use the strengths of both languages are valuable because they have NO LIMITS. Machine Le...
Today I am happy to announce that a new tidymodels-centric version of my free, online, interactive course, Supervised Machine Learning: Case Studies in R, has been published! 🎉 This is at least the third version of this course I’ve built at this point 😁 but I believe it to be the best, in terms of how it communicates machine learning...
In our last post, we applied machine learning to the Capital Aset Pricing Model (CAPM) to try to predict future returns for the S&P 500. This analysis was part of our overall project to analyze the various methods to set return expectations when seeking to build a satisfactory portfolio. Others include historical averages and discounted cash flow models we...
RBloggers|RBloggers-feedburner I am happy to announce that RAthena-1.9.0 and noctua-1.7.0 have been released onto the cran.
