Description: This basic programming course with R for aspiring data analysts is designed to accompany a beginner in programming, from the basics of the programming language (one of the best known and most widely used in the field of data analysis) to the use of descriptive statistics.At the end of this course the student will be able to create, import, manipulate and manage datasets. The course starts with setting up the working environment: we will see how to download, install and use some of the most important tools for using R, such as RStudio. We will then move on to the creation of objects: R is based on certain structures that we need to know, such as vectors, matrices, lists and dataframes. Once we understand how to create and manipulate these data structures, extract elements from them and save them locally on the computer, we will move on to the use of loops and the creation of functions. In the next section, we will look at a number of useful topics: how to set up a working directory, how to install and retrieve a package, how to get information about data, where to find datasets for testing, and how to get help with a function.When analysing data, one sooner or later comes across dataframes known as variable x-cases. We will therefore see how to import a dataframe from your computer, or from the internet, into R. There are many functions that are suitable for this purpose, and many packages that are useful for importing data that is in some particular format, such as the formats for Excel, .csv, .txt or JSON.We will then see how to manipulate data, create new variables, aggregate data, sort them horizontally and longitudinally, and merge two datasets. To do this, we will use some specific packages and functions, such as dplyr, tidyr or reshape2. We will also briefly see how to interface with a database and use other packages to streamline the management of somewhat larger datasets. R is also a very im
