Feed: Planet big data. Author: Curt Monash. May 20, 2018 The tech industry has a broad range of political concerns. While I may complain that things have been a bit predictable in other respects, politics is having real and new(ish) technical consequences. In some cases, existing technology is clearly adequate to meet regulators’ and customers’ demands. Other needs look more like open research challenges. 1. Privacy regulations will be very different in different countries or regions. For starters: This is one case in which the European Union’s bureaucracy is working pretty well. It’s making rules for the whole region, and ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Nishtha Saxena. Data is growing every minute, and it’s not showing any sign of stopping. The pylon holding up the commercial enterprise of today is information – and it’s been the same way for decades. Petabytes and Exabytes of data racing through the information expressway of the 21st century, however have companies across the world scurrying to assimilate the most audacious datasets possible – all in the hope of gleaning that extra insight, that extra edge, over the others in the race. If you aren’t leveraging data, your own or from ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A maintenance update of RcppGSL just brought version 0.3.5 to CRAN, a mere twelve days after the RcppGSL 0.3.4. release. Just like yesterday’s upload of inline 0.3.15 it was prompted by a CRAN request to update the per-package manual page; see the inline post for details. The RcppGSL package provides an interface from R to the GNU GSL using the Rcpp package. No user-facing new code or features were added. The NEWS file entries follow below: Changes in version 0.3.5 (2018-05-19) Update package manual page using references to DESCRIPTION file [CRAN request]. Courtesy ... Read More

Feed: R-bloggers. Author: aghaynes. The openrouteservice provides a new method to get geodata into R. It has an API (or a set of them) and an R package has been written to communicate with said API(s) and is available from GitHub. I’ve just been playing around with the examples on this page, in the thought of using it for a project (more on that later if I get anywhere with it). Anyways…onto the code…which is primarily a modification from the examples page I mentioned earlier (see that page for more examples). devtools::install_github("GIScience/openrouteservice-r") Load some libraries library(openrouteservice) library(leaflet) Set the API ...

Feed: R-bloggers. Author: Carl Goodwin. With tensions heightened recently at the United Nations, one might wonder whether we’ve drawn closer, or farther apart, over the decades since the UN was established in 1945. We’ll see if we can garner a clue by performing cluster analysis on the General Assembly voting of five of the founding members. We’ll focus on the five permanent members of the Security Council. Then later on we can look at whether Security Council vetoes corroborate our findings. A prior article, entitled the “cluster of six“, employed unsupervised machine learning to discover the underlying structure of voting data ... Read More

Feed: R-bloggers. Author: Akshay Vaghani. If you ever pass outside a restaurant in New York City, you’ll notice a prominently displayed letter grade. Since July 2010, the Health Department has required restaurants to post letter grades showing sanitary inspection results. An A grade attests to top marks for health and safety, so you can feel secure about eating there. But you don’t necessarily know that you will enjoy the food and experience courteous service. To find that out, you’d refer to the restaurant reviews. For this project, I looked at a simple data analysis and visualization of the NYC restaurants ... Read More

Feed: R-bloggers. Author: rOpenSci - open tools for open science. The drake R package is not only a reproducible research solution, but also a serious high-performance computing engine. The Get Started page introduces drake, and this technical note draws from the guides on high-performance computing and timing. You can help! Some of these features are brand new, and others are newly refactored. The GitHub version has all the advertised functionality, but it needs more testing and development before I can submit it to CRAN in good conscience. New issues such as r-lib/processx#113 and HenrikBengtsson/future#226 seem to affect drake, and more ... Read More

Problem Image that someone in a bank want to find out whether some of bank’s credit card holders are acctually the same person, so according to his experience， he set a rule: the people share either the same address or the same phone number can be reasonably regarded as the same person. Just as the example: library(tidyverse) a In the dataframe ]czoxOlwiYVwiO3tbJiomXX0=[ , the letters in column ]czo0OlwiYWRkclwiO3tbJiomXX0=[ stand for address information, the numbers in column ]czo1OlwicGhvbmVcIjt7WyYqJl19[ stand for phone numbers, and the integers in column ]czo0OlwiZmxhZ1wiO3tbJiomXX0=[ is what he want: the CLUSTER flag which ...

Feed: R-bloggers. Author: Lauren Tessier. The Decision Analysis in R for Technologies in Health (DARTH) workgroup is hosting a two-day workshop on decision analysis in R in Leiden, The Netherlands from June 7-8, 2018. A one-day introduction to R course will also be offered the day before the workshop, on June 6th. Decision models are mathematical simulation models that are increasingly being used in health sciences to simulate the impact of policy decisions on population health. New methodological techniques around decision modeling are being developed that rely heavily on statistical and mathematical techniques. R is becoming increasingly popular in decision ... Read More
