Feed: R-bloggers. Author: R Views. Roland Stevenson is a data scientist and consultant who may be reached on Linkedin. When accessing an API or database in R, it is often necessary to provide credentials such as a login name and password. You may find yourself being prompted with something like this: When writing an R script that requires a user to provide credentials, you will want a way to have the script prompt the user or, better yet, programatically provided the credentials in the R script. Either way, be careful! You don’t want to put your credentials out there in ... Read More

Feed: R-bloggers. Author: quantixed. Our lab is international. People born all over the world have come to work in my group. I’m proud of this fact, especially in the current political climate. I’ve previously used the GoogleMaps API to display a heat map on our lab webpage. It shows where in the world people in the lab come from. This was OK, but I wanted to get an R based solution to make this graphic to make it easier to automate updates. This post is an explainer and “how to” guide. Code and some example data are here. The idea ... Read More

Feed: All - O'Reilly Media. Author: Tim O'Reilly. Gradual steps (source: Pixabay) This post was originally published on Quartz. The pursuit of monopoly has led Silicon Valley astray. Look no further than the race between Lyft and Uber to dominate the online ride-hailing market. Both companies are gearing up for their IPOs in the next few months. Street talk has Lyft shooting for a valuation between $15 and $30 billion dollars, and Uber valued at an astonishing $120 billion dollars. Neither company is profitable; their enormous valuations are based on the premise that if a company grows big enough and ... Read More

Feed: R-bloggers. Author: Econometrics and Free Software. There’s a lot going on in the development version of {tidyr}. New functions for pivoting dataframes, pivot_wide() and pivot_long() are coming, and will replace the current functions,spread() and gather(). spread() and gather() will remain in the package though: You may have heard a rumour that gather/spread are going away. This is simply not true (they’ll stay around forever) but I am working on better replacements which you can learn about at https://t.co/sU2GzWeBaf.

Feed: R-bloggers. Author: Bob Muenchen. In my previous post, I discussed Gartner’s reviews of data science software companies. In this post, I show Forrester’s coverage and discuss how radically different it is. As usual, this post is already integrated into my regularly-updated article, The Popularity of Data Science Software. Forrester Research, Inc. is another company that reviews data science software vendors. Studying their reports and comparing them to Gartner’s can provide a deeper understanding of the software these vendors provide. Historically, Forrester has conducted their analyses similarly to Gartner’s. That approach compares software that uses point-and-click style software like KNIME, to ... Read More

Drawn by the allure of frictionless acquisitions, vendorless negotiations, and the open source appeal to potential new talent, companies of all types and sizes now use open source technology to drive growth and innovation. Likewise, Apache Cassandra™ adoption has increased significantly since Facebook open sourced the project in 2008. Designed for the modern world, Cassandra enables organizations to build transformative applications that have outgrown the capabilities of traditional relational databases ... Read More

Feed: Planet big data. Author: Matthew Guarini. It’s Time To Start Talking About Professional Licensing For Software Engineers It wasn’t until enough boilers blew up that mechanical engineers had to get licensed. It wasn’t until bridges and buildings started collapsing that civil engineers and architects had to get licensed. Now that airplanes are falling out of the sky due to automation (AKA, “software”) errors in the anti-stall systems, isn’t it time that software engineers have to get licensed? We buy, build, or trust many software- (and now AI-) controlled systems to protect our lives. How long are we going treat ... Read More

Feed: Big Data Made Simple. Author: Megan Mary Jane. With Tax Day (April 15th) fast approaching in the US, time is running out to file your returns before the deadline. If you’re one of the 1 in 3 Americans who don’t get around to filing their taxes until April, you’ll know that waiting until the last minute is never ideal. However, stress isn’t the only potential problem you face when you’re in a time crunch. If you have to rush the complex process of tax filing because the deadline is looming, you’re more inclined to cut corners when it comes ... Read More
