Cookbook for R How to include custom library into maven local repository? There are 2 cases that you need to issue Maven’s command to include a jar into the Maven local repository manually. The jar you want to use doesn’t exist in the Maven center repository.You created a custom jar, and need to use for another Maven project. P.S Trust me, there are still many jars that doesn’t support Maven. Case study For example, kaptcha, a popular third party Java library, which is used to generate “captcha” image to stop spam, but it’s not available in the Maven center repository. In this tutorial, we will show you how to install the “kaptcha” jar into your Maven’s local repository. 1. mvn install Download the “kaptcha“, extract it and copy the kaptcha-version.jar to somewhere else, for example, c drive. mvn install:install-file -Dfile=c:\kaptcha-{version}.jar -DgroupId=com.google.code -DartifactId=kaptcha -Dversion={version} -Dpackaging=jar Demo.

alyssa frazee Thu 02 January 2014 | -- (permalink) My sister is a senior undergraduate majoring in sociology. She just landed an awesome analyst job for next semester and was told she'll be using some R in the course of her work. She asked me to show her the ropes during winter vacation, and of course I said yes! One catch: the day we planned to work, it turned out we only had an hour of overlapping free time. Challenge accepted. (1) download R and RStudio I'm impressed that RStudio is both accessible/helpful for beginners and useful for experts. (2) console and script The first thing we did after getting set up was type two lines into the console: It wasn't exactly "hello world", but it illustrated some concepts like "assignment" and "variables" and "evaluation"2. The next thing I had my sister do was save those two lines of code in an R script. (3) comments # COMMENTS ARE SUPER IMPORTANT so we learned about them (4) graphics x = rnorm(1000, mean = 100, sd = 3) hist(x) (5) getting help (6) data types vectors

Ruby on Rails par la pratique - Commencer avec Ruby on Rails Ce guide s'inspire du site « Rails Guides », de mon expérience personnelle de Ruby on Rails et dans tout un tas d'autres ressources (screencasts, sites communautaires, etc...). Ce guide est également l'occasion de constituer une application de A à Z, d'en voir tous les tenants et les aboutissants (conception, codage, déploiement, etc...). Je vous souhaite d'ores et déjà une très bonne lecture ! Dans ce guide, je pars du principe que le lecteur possède une connaissance minimale du langage Ruby. Pour commencer avec Ruby on Rails, il est nécessaire d'avoir au moins trois choses installées : Ruby (version 1.8.7 dans le cas de ce guide) Rubygems (version 1.3.2 dans le cas de ce guide) SQLite, MySQL, ou PostgreSQL Rails est un framework de développement web écrit en langage Ruby. Le développement avec Rails nécessite l'apprentissage de bonnes pratiques de développement. La philosophie de Rails se base sur trois principes : III-A. III-B.

R Moves Up From #9 to #6, But What Does It Mean to Really be Proficient in a Language? There's been a lot of noise in the data science community this past week about IEEE Spectrum's 2015 language rankings, where R moved up three notches from #9 in 2014 to #6 in 2015. The Spectrum post gives some lip service to needing to know a domain in addition to just the language itself. But here I drill down into what it means to really know a language.

bookdown: Easy Book Publishing with R Markdown R for Data Science Learn R : 12 Free Books and Online Resources – YOU CANalytics Please read the disclaimer about the Free PDF Books in this article at the bottom R, an open-source statistical and data mining programming language, is slowly but surely catching up in its race with commercial software like SAS & SPSS. I believe R will eventually replace SAS as the language of choice for modeling and analysis for most organizations. The primary reason for this is plainly commercial. Most organizations are questioning the heavy annual cost of SAS on their P&L statement. This is escalated with the presence of R as a free and viable replacement.
