In this post, I present something I am currently investigating (feedback welcome!) and that I am implementing in my new package {bigutilsr}. This package can be used to detect outlier samples in Principal Component Analysis (PCA). remotes::install_github("privefl/bigutilsr") library(bigutilsr) I present three different statistics of outlierness and two different ways to choose the ...

Feed: SAS Blogs. Author: Inge Krogstad. IT managers see the potential for cost-cutting from transitioning application development to open source software (OSS). Today, companies can hire recent college graduates with skills in open source development and avail themselves of the free software. But is all that glitters really gold? Users groups and more formal workgroups are experiencing an avalanche of new routines that have been made available. And users are now sharing programs along with their own cutting-edge ideas, whether based on R, Python, Tensorflow, or another programming language or library. Therefore, it has to be assumed that business leaders ... Read More

This will be Part 1 of what I hope to be a multi-part series ofplotting soccer event-level data with R! This is more of a tutorial blogpost rather than a deep analytical piece but I will give some context tothe examples to set the scene! I can’t give an exact ... Read More

Since this morning, Rcpp stands at just over 1750 reverse-dependencies on CRAN. The graph on the left depicts the growth of Rcpp usage (as measured by Depends, Imports and LinkingTo, but excluding Suggests) over time. Rcpp was first released in November 2008. It probably cleared 50 packages ... Read More

Feed: R-bloggers. Author: AbdulMajedRaja RS. Topic Extraction is an integral part of IE (Information Extraction) from Corpus of Text to understand what are all the key things the corpus is talking about. While this can be achieved naively using unigrams and bigrams, a more intelligent way of doing it with an algorithm called RAKE is what we’re going to see in this post. Udpipe udpipe is an NLP-focused R package created and opensourced by this organization bnosac. Thanks to them, udpipe is the R package that many a times solves the pain of not having native spacy for R. Udpipe ... Read More

Feed: Planet MySQL; Author: Michael McLaughlin; While building my student image on Fedora 30, I installed the MySQL PHP Connector (php-mysqlndrp) but neglected to install the Python Connector. This adds the installation and basic test of the Python Connector to the original blog post. You use the following command with a wildcard as a privileged user. The wildcard is necessary because you need to load two libraries to support Python 2.7 and 3.7, which are installed on Fedora 30. You also need to be the root user or a user that is found in the sudoer’s list: yum install -y ... Read More

Feed: Cloudwards. Author: Jacob Roach; Neither Namecheap or GoDaddy made it into our best web hosting guide, but one was much closer than the other. As two domain-registrars-turned-web-hosts, it only seemed fitting to pit the two against each other in a Namecheap vs. GoDaddy matchup. Although GoDaddy has a significantly larger market share, it isn’t necessarily the best option.  GoDaddy isn’t a stranger to our comparisons, taking on some of the biggest names in the industry in our SiteGround vs. GoDaddy and HostGator vs. GoDaddy head-to-heads. Namecheap, on the other hand, is a newcomer, rarely starring in our guides. Nevertheless, ... Read More

Feed: R-bloggers. Author: rOpenSci - open tools for open science. The free online book Open Forensic Science in R was created to foster open science practices in the forensic science community. It is comprised of eight chapters: an introduction and seven chapters covering different areas of forensic science: the validation of DNA interpretation systems, firearms analysis of bullets and casings, latent fingerprints, shoe outsole impressions, trace glass evidence, and decision-making in forensic identification tasks. The chapters of Open Forensic Science in R have the same five sections: Introduction, Data, R Package(s), Drawing Conclusions, and Case Study. There is R code ... Read More

Feed: R-bloggers. Author: R on The broken bridge between biologists and statisticians. Fitting mixed models has become very common in biology and recent developments involve the manipulation of the variance-covariance matrix for random effects and residuals. To the best of my knowledge, within the frame of frequentist methods, the only freeware solution in R should be based on the ‘nlme’ package, as the ‘lmer’ package does not easily permit such manipulations. The ‘nlme’ package is fully described in Pinheiro and Bates (2000). Of course, the ‘asreml’ package can be used, but, unfortunately, this is not freeware. Coding mixed models in ... Read More

Feed: R-bloggers. Author: Keith Goldfeld. I’m developing study simulations that require me to generate a sequence of health status for a collection of individuals. In these simulations, individuals gradually grow sicker over time, though sometimes they recover slightly. To facilitate this, I am using a stochastic Markov process, where the probability of a health status at a particular time depends only on the previous health status (in the immediate past). While there are packages to do this sort of thing (see for example the markovchain package), I hadn’t yet stumbled upon them while I was tackling my problem. So, I ... Read More
