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: Blog Post – Corporate – DataStax. Author: Jim Hatcher, Principal Architect. Microservices are starting to take over nearly every aspect & angle of modern enterprises In one survey of more than 350 senior development stakeholders, 91% said they are currently using or have plans to use microservices and 92% said they increased their number of microservices in the last year.

Feed: Blog – ArangoDB. Author: Willi Goesgens. This is an update of the 2016 blog post How to put ArangoDB to Spartan-Mode. A lot of things have changed in the last years. We moved our API implementation from JavaScript to C++. ArangoDB now has a new (default) storage engine, namely RocksDB instead of MMFiles. RocksDB is a great storage engine. However, it also trades memory for speed. If you start with the default configuration you might end up with using much more memory for ArangoDB than expected. Therefore let’s focus on our new storage engine, and make a configuration to ... Read More

Feed: R-bloggers. Author: Econometrics and Free Software. There’s a lot going on in the development version of {tidyr}.

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
