Feed: R-bloggers. Author: R Views. In previous posts, we covered how to run a Monte Carlo simulation and how to visualize the results. Today, we will wrap that work into a Shiny app wherein a user can build a custom portfolio, and then choose a number of simulations to run and a number of months to simulate into the future. A link to that final Shiny app is here and here is a snapshot: We will use RMarkdown to build our Shiny application by inserting runtime: shiny into the yaml header. This will alert the server (or our laptop) that ... Read More

Feed: R-bloggers. Author: Peter Prevos. We all hate the experience of calling a service provider and being placed on hold for a very long time. Organisations that take their level of service seriously plan their call centres so that the waiting times for customers is within acceptable limits. Having said this, making people wait for something can in some instances increase the level of perceived value. Call centre performance can be expressed by the Grade of Service, which is the percentage of calls that are answered within a specific time, for example, 90% of calls are answered within 30 seconds ...

Feed: Planet big data. Author: David Smith. he fourteenth annual worldwide R user conference, useR!2018, was held last week in Brisbane, Australia and it was an outstanding success. The conference attracted around 600 users from around the world and — as the first held in the Southern hemisphere — brought many first-time conference-goers to useR!. (There were also a number of beginning R users as well, judging from the attendance at the beginner's tutorial hosted by R-Ladies.) The program included 19 3-hour workshops, 6 keynote presentations, and more than 200 contributed talks, lightning talks and posters on using, extending, and deploying R. If you ... Read More

Feed: R-bloggers. Author: rOpenSci - open tools for open science. R packages are widely used in science, yet the code behind them often does not come under scrutiny. To address this lack, rOpenSci has been a pioneer in developing a peer review process for R packages. The goal of pkginspector is to help that process by providing a means to better understand the internal structure of R packages. It offers tools to analyze and visualize the relationship among functions within a package, and to report whether or not functions’ interfaces are consistent. If you are reviewing an R package (maybe ... Read More

Feed: R-bloggers. Author: Bernardo Lares. To automate the process of modeling selection and evaluate the results with visualization, I have created some functions into my personal library and today I’m sharing the codes with you. I run them to evaluate and compare Machine Learning models as fast and easily as possible. Currently, they are designed to evaluate binary classification models results. Before we start, let me show you the final outcome so you know what we are trying to achieve here with just a simple R function: So, let’s start! The results object First of all, we need to have ...

Feed: R-bloggers. Author: nsaunders. Dual-axes at tipping-point Sydney’s congestion at ‘tipping point’ blares the headline and to illustrate, an interactive chart with bars for city population densities, points for commute times and of course, dual-axes. Yuck. OK, I guess it does show that Sydney is one of three cities that are low density, but have comparable average commute times to higher-density cities. But if you’re plotting commute time versus population density…doesn’t a different kind of chart come to mind first? y versus x. C’mon. Let’s explore. First: do we even believe the numbers? Comments on the article point out that ... Read More

Feed: Big Data Made Simple - One source. Many perspectives.. Author: Baiju NT. Data has grown increasingly complex over recent years, thanks in no small part to computers becoming fundamental to how all businesses work. This has its positives, as the more data and metrics a company can work with, the more performant and reactive the be. The real problem is that many people are very visually-oriented, meaning a wall of text, numbers and technical terms simply aren’t all that digestible, even to people who understand what all this information means. Thankfully, people long ago mastered the creation of charts, ... Read More
