EDA de datos de INEGI

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.

Efficiency comparison of dplyr and tidyr functions vs base R

A couple of years ago I was interested in the efficiency of R when it comes to time processing and management of memory and I read a few blog posts about this topic, particularly pointing at the fact that R hasn’t been designed to be a very efficient language, especially when it comes to big data processing, and this could be its doom at some point in the future. By that time I also read a great article or blog post regarding the complexity of using the tidyverse family of packages in R, especially with the task of teaching R to beginners.

Mini tutorial: hacer tipo lógico cualquier texto

Acerca de este post. Este es mi primer post en español. Es en realidad la traducción de un post que escribí originalmente en inglés hace un par de meses. Pueden ver el post original aqui. Espero que sea útil para la comunidad hispanohablante de usuarios de R. Este post se basa en un trabajo reciente donde mi tarea fue la revisión y depuración de piezas de código pequeñas o simples que pueden resultar en consejos prácticos y rápidos para otros usuarios de R, especialmente principiantes o personas sin mucha experiencia en el uso de R.

Minitutorial: make_logical any string

Welcome to R minitutorials of R White Dwarf Since the beginning of this year I’ve been forced to abandon completely the blog for countless and rather abstract personal reasons that include personal health, family matters and changes in my daily activities including volunteer work as well as main job. As part of the last, I finally got hired for a position as R developer, which brings great joy to me.

R function to fill in merged cells

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.

Functions in R

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.
