This document provides an overview of the R programming language. It describes R as a functional programming language for statistical computing and graphics that is open source and has over 6000 packages. Key features of R discussed include matrix calculation, data visualization, statistical analysis, machine learning, and data manipulation. The document also covers using R Studio as an IDE, reading and writing different data types, programming features like flow control and functions, and examples of correlation, regression, and plotting in R.
This document summarizes a seminar presentation on the R programming language. It begins with an introduction to R's history and features. Key points covered include that R is a functional programming language developed for statistical analysis. It has a large number of built-in statistical functions and packages. The document then discusses R packages, graphical user interfaces, getting started with basic objects and functions, and programming features like flow control and functions. Examples are provided. Reasons for using R include its matrix calculation, data visualization and statistical analysis capabilities. Comparisons are made to other languages like Python and Java. The document concludes that R has become a high-quality open-source software for statistical computing and graphics.
I studied the inner working of spot markets inside Italian Power EXchange and I analysed the results of prices in these ones to look for a stochastic SARIMA model in order to forecast the prices.
I studied the steel industrial domain and the model of a simulator (developped by Iso Sistemi S.r.l.) of the industrial plant of Piombino in order to get the expected energy consumption. Then I design and develop a platform that contains the predictive model and the simulator. The platform is able to generate different scenarios of purchase by the various energy markets, and further to select the best scenario for minimizing overall costs of energy according to the production plan established.
I also analyse ex-post the gain of using this platform using actual datas about consumption of the steel plant of Terni for Genuary 2013. The platform improves the total cost of energy purchase, and the saving is near to the best solution that you can select in retrospect.
Final Mark: 110/110 cum laude
R is a statistical and graphical programming language that is easy to use and powerful. It is free and exists on many platforms. The number of R users has been growing substantially each year as it has become the lingua franca of data science. R allows for data import, analysis, and visualization through functions, packages, and libraries. Common data types in R include vectors, matrices, data frames, factors, and lists which allow for storing and manipulating different types of data.
The document introduces the topic of data science and the programming language R. It defines data science and provides examples of using data science for social good. Additionally, it outlines some of the main features and pros and cons of using R for data science applications and statistical analysis.
Basic introduction to "R", a free and open source statistical programming language designed to help users analyze data sets by creating scripts to increase automation. The program can also be used as a free substitute for Microsoft Excel.
R programming language: conceptual overviewMaxim Litvak
This is an advanced overview of the programming language R showing the concepts and paradigms used there.
Target audience: R programmers who want to see the big picture and software engineers who have a broad experience in other technologies and want to grasp how R is designed.
R is a programming language and software environment for statistical analysis and graphics. It allows for effective data manipulation, storage, and graphical display. Some key features of R include being free and open source with many contributed packages, having simple yet elegant code, and the ability to perform statistical analysis and visualization. The R studio interface has components for running code in the console, editing code in the editor, and viewing outputs like plots and help documentation. Common data structures in R include vectors, matrices, lists, and data frames.
This document outlines the agenda for a two-day workshop on learning R and analytics. Day 1 will introduce R and cover data input, quality, and exploration. Day 2 will focus on data manipulation, visualization, regression models, and advanced topics. Sessions include lectures and demos in R. The goal is to help attendees learn R in 12 hours and gain an introduction to analytics skills for career opportunities.
R is a programming language for statistical analysis and graphics. It is an open-source language developed by statisticians to allow for easy statistical analysis and visualization of data. The document provides an overview of R, discussing its origins, functionality, uses in data science, and popular packages and IDEs used with R. Examples are given of basic R syntax for vectors, matrices, data frames, plotting, and applying functions to data.
An Interactive Introduction To R (Programming Language For Statistics)Dataspora
This is an interactive introduction to R.
R is an open source language for statistical computing, data analysis, and graphical visualization.
While most commonly used within academia, in fields such as computational biology and applied statistics, it is gaining currency in industry as well – both Facebook and Google use R within their firms.
Presentation on R programming. Topics covered are: Manage your Workspace
Data types
Fiddle with Data Types
Lists Vs Vectors
R as calculator!!!
Decision making statements, looping, functions
Interact with R!!!
Visualization!!!
Time for U!!!
Clustering
Regression (with curve fitting)
The document discusses how personalization and dynamic content are becoming increasingly important on websites. It notes that 52% of marketers see content personalization as critical and 75% of consumers like it when brands personalize their content. However, personalization can create issues for search engine optimization as dynamic URLs and content are more difficult for search engines to index than static pages. The document provides tips for SEOs to help address these personalization and SEO challenges, such as using static URLs when possible and submitting accurate sitemaps.
