Easy Emacs To start using R, or almost anything else in Emacs you basically need to know 3 things: 1) How to move in Emacs, meaning understanding what is what and learning a few key commands; 2) What is the configuration file and how to use it and 3) How to use packages to extend Emacs. In the first half of this post I will try to show how easy it is to cover these 3 points even for people who are inexperienced in programming.

Introducción El análisis exploratorio de datos (EDA en inglés, “Exploratory Data Analysis”) es una de las herramientas más útiles en varias áreas de análisis de datos. El concepto de EDA ha sido utilizado popularmente en los últimos años para referirse a los procesos de exploración primaria de un grupo de datos. Por lo tanto, no existe una fórmula o receta para realizar una exploración, sea general o exhaustiva. Una exploración correcta depende de las habilidades del analista tanto para entender los datos como para utilizar las herramientas adecuadas.

This post is part of our series on functions in R. You can see our previous post if you want to understand the basics but it is not strictly necessary. Here we will go into detail about for loops and if statements in R, two key elements of any function. We are going to define a process, map it in a step-by-step approach and wrape it in a function that can repeat it automatically.

Background This is the first post of R with White Dwarf and I decided to start this blog with a basic tutorial. There is already a lot of information in the web about getting started with R. With a simple google search you can easily find info on how to install it, how to use R studio or other text editor, learn about the basic functions and concepts, what is a vector, a data frame, how to use them, etc.
