2 About the R-Academy The R Academy of eoda is a modular course program for the R statistical language with regular events and training sessions. Our course instructors have been working with data analysis for over 10 years. The course concept is aimed to train you to become an R expert. Depending on your needs and interests, you can choose from a variety of different course modules. A strictly hierarchical structure does not exist, and the modules can be combined individually. Our R training at universities, graduate centers as well as for companies are regularly evaluated and rated very well. About R R, which is an object oriented programming language for statistical data analysis, is the best alternative for the analysis and visualization of data, data mining, and business intelligence. R is extremely powerful and very flexible in comparison to most of the big commercial software packages for data analysis. Plus, R is open source and is constantly being developed by a global scientific community. Hence, R sets an unprecedented standard of functionality, quality and contemporariness. The fact that the scientific community as well as big companies such as IBM, SAS and Revolution Analytics engage so heavily in R, creates a strong investment reliability for R users. The programming language R provides users with a large spectrum of functions reaching far beyond the application of traditional statistics. As of now, R is in the process of becoming the multi-platform lingua franca of data analysis today there are more than R extension packages available on CRAN, which support data analysis in every way possible as well as imaginable.

8 Interactive Graphics with R I 2 days Interactive graphics are a flexible and efficient way to analyze data and to present analysis results. Interactive graphic applications offer queries, selections, highlighting or the modification of graphics parameters. In the environment of R, there are various concepts that provide the possibility to create interactive graphics and applications directly out of R. The course presents an overview of the creation of interactive graphics with R and provides the tools to independently implement interactive visualizations in R. Course content ggvis rcharts shiny.
9 Data Mining with R I 2 days Data Mining indicates a set of methods extracting knowledge from datasets without having presumptions about the data structure. Statistical und mathematical techniques are applied on data to expose inherent patterns. Generally the methods don t need a high level of measurement (categorical, ordinal or metric scale) while they have the capability to release complex non-linear data relations. Universal applications for Data Mining methods are forecast-models, basket of goods analysis, target group analysis and more. Methods which are part of the course: Regression- and Classification Trees Random Forest Artificial Neural Networks Support Vector Machines K-Means-Clustering
10 Multivariate Statistics with R I 2 days Cluster Analysis Starting point and Theory, different distance measures, Interpretation, Visualization Cluster Analysis Factor Analysis Starting point, Suitability, number of factors, number of extracting dimensions Regression analysis Modell, interpretation, possible problems Multivariate Statistics with R II Confirmatory factor analysis Multi Dimensional Scaling Shapley Value Regression Discriminant Analysis Bootstrapping
11 Big Data and Hadoop with R I 1 day Various initiatives have developed different concepts to cope with Big Data. For example different parser and packages have been developed to facilitate the handling of Big Data in R. Data in scattered systems require different methods of analysis than not-scattered data do. The principle of MapReduce is to divide problems into small tasks which can be solved on a small part of data. A typical example of application of data, which are saved in a Hadoop- System, is the counting of word in text files. Conventional techniques work through the whole text en bloc which can be really timeconsuming. MapReduce fragments the text into single knots and small blocks. The Reduce-Part reunites the results. Even complex search-, compare-, and analysis operations can be parallelized in this way and can therefore be calculated faster. The course does convey the development of scripts for MapReduce jobs with concrete examples. The course will give an introduction to the following aspects: Connection to data sources like data bases or file systems as Hadoop Linking to cloud environments like WindowsAzure or Amazon Web Services Chunking Partitition of data into sub parts Parallelization of jobs for calculation Overview over different parser s concepts (Revolution Analytics, Oracle R Enterprise, Renjin, ) Visualization of Big Data
12 Text Mining with R I 2 days As a discipline of Data Mining, Text Mining includes algorithm based analysis methods for the detection of structures and information from texts by using statistical and linguistic analysis tools. An example of application is the Web Mining, which can identify trends and customer requirements on websites and social media platforms. Text Mining is also used to forecast price trends and stock prices on the basis of news reports. The course focuses on the application of the packets tm, RTextTools and OpenNLP and covers the following aspects: Overview of Text Mining Import of unstructured data, Web Scraping Structuring of texts (Pruning, Tokenization, Sentence Splitting, Normalization, Stemming, N-Gramme) Simple content analysis and association analysis Classification of documents with different methods (Support Vector Machines, Generalized Linear Model, Maximum Entropy, Supervised latent Dirichlet allocation, Boosting, Bootstrap aggregating, Random Forrests, Neural Networks, Regression Tree)
13 Advertising-Effectiveness Measurement with R I 1 day The assessment of advertising material used and its efficiency is still one of the major challenges of marketing. The course is focusing on the analysis of information from the web tracking.
14 Applied Statistics in Quality Management with R I 3 days Statistical Controlling of incoming goods in production, and outgoing goods generate operating figures necessary to rate the quality of goods and products. The requirements to process quality controls systematically are methodical knowledge of statistics as well as of the right software. The open source statistical language R represents an interesting alternative. The course conveys basic knowledge concerning R which can be used to manage previously processed statistical data. Before they are processed practically with R, the concepts of statistical testing will be introduced theoretically. Furthermore AQL standard values according to ISO 2859 and DIN ISO 3951 will be discussed. Additionally their operation modes and application will be presented related to practical applications. The application of the methods in R covers the most important functions in the area of statistical testing and the development of quality control plans. Essential contents from the area of inference statistics include: How can the optimal size of a random sample be determined? How can a decision for a specific testing method be made? How can operating figures be interpreted? Which degree of safety does the result of the random sample contain? How can the risks of deliverers and customers be arranged? Which discrepancies are acceptable?
15 Programming with R I 2 days Loops and control elements Vector-valued programming Split-Apply-Combine Approach Define your own functions Environments and Scoping Object-oriented Programming / R-Class systems Exceptions / Error Handling Profilling and Debugging Data Management with R I 1 day Recoding of variables Data Aggregation Forming and analyze subsets of data and groups Groupwise data operations (split-apply-combine) Merging and Sorting Data Data transformations (wide vs. long format) Comparing data Identify and remove duplicates

17 Reproducible Research with R I 1 day The analysis of statistical data generate reports with various elements such as text, data, formulas, tables, and graphics. Interfaces between R and latex/html can bring the various contents in R together, and create a clear output which is available for presentation. In addition, it allows R to customize the reports dynamically on the basis of new data. In the method known under the term Reproducible Research the report items are updated without making any manual adjustments. After completion of the course, the participants should be able to create customized and automated reports. Contents of the course : The user interface R-Studio The packets " Sweave " and " knitr Short introduction to latex, Markdown and HTML Formatting the R-issues with Chunk options Making static report templates in various output formats such as pdf and html Dynamic reports and automated adjustments The combination of theoretical introductions, specific cases and practical exercises ensure the success of learning.
