The R Project for Statistical Computing Expressions idiomatiques-anglais Apprendre l'anglais > Cours & exercices d'anglais > Exercices d'anglais > test d'anglais n°93758 : Expressions idiomatiques - cours Pour parler anglais naturellement, il est essentiel de connaître quelques expressions idiomatiques. En voici une liste. Pour chacune des expressions, on donnera la traduction française et la traduction littérale (= la traduction qu'on obtient en traduisant chaque mot l'un après l'autre). Après avoir appris ces 10 expressions, faites l'exercice suivant. Exercice : Compléter l'expression idiomatique correspondant à la phrase donnée. Merci de votre participation ! Essayez d'abord de faire le test sans les explications grises. Fin de l'exercice d'anglais "Expressions idiomatiques - cours"Un exercice d'anglais gratuit pour apprendre l'anglais.

Syntax Highlighting on Blogger - Gist Here is another way to paste code into blogger with nice syntax highlighting.Go to the code you want to postCopy the embed tagGo back to blogger, and select "Edit Html"Paste the embed tag into your postBelow is the example source code using this tag: A potential drawback of this approach might be the stability of github as a company. In a downturn, it may shut down with very short notice. Compare to using SyntaxHighlighter, personally, I think this approach is way better: No setup required (in a previous post I documented how to setup syntaxhighlighter for blogger, it took me half an hour to setup everything correctly. To paste script like below used to require replacing '<' with &lt; and '>' with &gt; manually.

An Introduction to R Table of Contents This is an introduction to R (“GNU S”), a language and environment for statistical computing and graphics. R is similar to the award-winning1 S system, which was developed at Bell Laboratories by John Chambers et al. It provides a wide variety of statistical and graphical techniques (linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, ...). This manual provides information on data types, programming elements, statistical modelling and graphics. This manual is for R, version 3.1.0 (2014-04-10). Copyright © 1990 W. Permission is granted to make and distribute verbatim copies of this manual provided the copyright notice and this permission notice are preserved on all copies. Preface This introduction to R is derived from an original set of notes describing the S and S-PLUS environments written in 1990–2 by Bill Venables and David M. Comments and corrections are always welcome. Suggestions to the reader 1.1 The R environment Try ?

Visualization The followings introductory post is intended for new users of R. It deals with interactive visualization using R through the iplots package. This is a guest article by Dr. Robert I. Kabacoff, the founder of (one of) the first online R tutorials websites: Quick-R. For readers of this blog, there is a 38% discount off the “R in Action” book (as well as all other eBooks, pBooks and MEAPs at Manning publishing house), simply by using the code rblogg38 when reaching checkout. Let us now talk about Interactive Graphics with the iplots Package: Interactive Graphics with the iplots Package The base installation of R provides limited interactivity with graphs. While playwith and latticist allow you to interact with a single graph, the iplots package takes interaction in a different direction. The iplots package is implemented through Java and the primary functions are listed in table 1. Table 1 iplot functions To understand how iplots works, execute the code provided in listing 1.

Help Changes from VPython 5 VPython 6 will run almost all old VPython programs correctly without change The following details about changes may be important in a few unusual cases. An animation loop must contain a rate or sleep statement, which limits the number of loop iterations per second as before but also when appropriate (about 30 times per second) updates the 3D scene and handles mouse and keyboard events. You should use the new function sleep rather than time.sleep. You must import visual or vis before importing graph or controls or filedialog, which most users have always done anyway. Be sure to read what's new in the latest version of VPython 6. Rotate and zoom To rotate the camera around the scene, drag with the right button down, or with the Ctrl key down. How to learn about VPython VPython is the Python programming language plus a 3D graphics module called "Visual" originated by David Scherer in 2000. For a quick introduction, see these YouTube videos: from visual import *
