Abstract
El presente documento pretende dar una visión general, partiendo desde un nivel básico de conocimiento sobre programación en R, sobre el manejo de datos bidimensionales, una de las estructuras de datos más empleadas en el análisis de datos y más esenciales en el software R. Se plantean las nociones más elementales como por ejemplo la creación de matrices y arrays, como modificarlos, pasando por nociones más avanzadas con funciones más concretas, pero de gran utilidad, como applay. Se hace especial hincapie en las operaciones matemáticas de matrices y como resolver sistemas de ecuaciones. Finalmente, se presentan una colección de tareas que se proponen para que el estudiante las intente realizar de forma autónoma una vez haya asentado el aprendizaje. Para que el aprendizaje sea más eficaz, el solucionario de tareas se presenta al final del documento
This document aims to give an overview, starting from a basic level of knowledge about programming in R, about handling two-dimensional data, one of the most used data structures in data analysis and the most essential in R software. Presenting the most elementary notions, such as the creation of matrices and arrays, how to modify them, going through more advanced notions with more specific functions, but very useful, such as applay. Special emphasis is placed on the mathematical operations of matrices and how to solve systems of equations. Finally, a collection of tasks are presented and proposed for the student to try to perform autonomously once learning has been finished. To make learning more effective, the task solution is presented at the end of the document
