C++11 Lambda Functions: Returns and Calls. In this entry in a series on lambda functions, Jeff Cogswell shows you how lambda functions can be stored in variables and walks you through how they can then be returned from a function and subsequently called by other functions. In our exploration of the new lambda features in C++11, we looked at how a lambda function can access the variables from the function containing the lambda function. Such a concept is common practice in a language such as JavaScript, and the JavaScript runtime will handle garbage collection by cleaning up data after it’s no longer needed. But what happens in C++? Let’s look at what goes on when a lambda function returns a variable from its containing function, which occurs when a function returns a lambda function. Look at the following code, and notice what I’m returning from the function called container: The function called container creates a lambda function, saves it in a variable called myfunc, and then returns the value of myfunc.

Conclusion. 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.

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 ? R and MongoDB. HTML5 - Web technology for developers. HTML5 is the latest evolution of the standard that defines HTML. The term represents two different concepts. It is a new version of the language HTML, with new elements, attributes, and behaviors, and a larger set of technologies that allows the building of more diverse and powerful Web sites and applications. This set is sometimes called HTML5 & friends and often shortened to just HTML5.

Designed to be usable by all Open Web developers, this reference page links to numerous resources about HTML5 technologies, classified into several groups based on their function. Semantics: allowing you to describe more precisely what your content is. Semantics Sections and outlines in HTML5 A look at the new outlining and sectioning elements in HTML5: <section>, <article>, <nav>, <header>, <footer> and <aside>.
