The Performanceanalytics Package The PerformanceAnalytics Package July 10, 2007 Type Package Title Econometric tools for performance and risk analysis. Version 0.9.5 Date 2007-06-29 Author Peter Carl, Brian G. Peterson Maintainer Brian G. Peterson <[email protected]> Description Library of econometric functions for performance and risk analysis. This library aims to aid practitioners and researchers in utilizing the latest research in analysis of non-normal return streams. In general, this library is most tested on return (rather than price) data on a monthly scale, but most functions will work with daily or irregular return data as well.

  • User! 2020 Tutorials – Afternoon Session
    useR! 2020 Tutorials – Afternoon Session How green was my valley - Spatial analytics with PostgreSQL, PostGIS, R, and PL/R by J. Conway This tutorial combines the use of PostgreSQL with PostGIS and R spatial packages. It covers data ingestion including cleaning and transformation, and basic analysis, of vector and raster based geospatial data from open sources. Learning outcomes: At the end of the tutorial, the participants will: • learn the advantages and disadvantages of using PostgreSQL, PostGIS, R, and PL/R to process geospatial data; • perform a basic installation and setup of the technology stack, including PostgreSQL, PostGIS, R, and PL/R; • gain experience on the data cleaning, subsetting, and ingestion process for that data; • perform several simply types of visualization and analysis on the ingested data. Requirements: The audience should be comfortable with R, SQL, and spatial data at an intermediate level. The attendees need only a modern OS/web browser. The hands-on exercises will be done via Katacoda. Creating beautiful data visualization in R: a ggplot2 crash course by S. Tyner Learning ggplot2 brings joy and “aha moments” to new R users, keeping them more engaged and eager to grow their R skills. Newer R users will be and feel more empowered with data visualization skills. In addition to experiencing joy in creating beautiful graphics, advanced R users will learn to take advantage of ggplot2’s elegant defaults, saving time on manual plotting tasks like drawing legends. Thus, time and energy can be spent on advanced analyses,

  • Computational Reproducibility in Archaeological Research: Basic Principles and a Case Study of Their Implementation
    J Archaeol Method Theory (2017) 24:424–450 DOI 10.1007/s10816-015-9272-9 Computational Reproducibility in Archaeological Research: Basic Principles and a Case Study of Their Implementation Ben Marwick1,2 Published online: 7 January 2016 # Springer Science+Business Media New York 2016 Abstract The use of computers and complex software is pervasive in archaeology, yet their role in the analytical pipeline is rarely exposed for other researchers to inspect or reuse. This limits the progress of archaeology because researchers cannot easily reproduce each other’sworktoverifyorextendit.Fourgeneralprinciplesofrepro- ducible research that have emerged in other fields are presented. An archaeological case study is described that shows how each principle can be implemented using freely available software. The costs and benefits of implementing reproducible research are assessed. The primary benefit, of sharing data in particular, is increased impact via an increased number of citations. The primary cost is the additional time required to enhance reproducibility, although the exact amount is difficult to quantify. Keywords Reproducible research . Computer programming . Software engineering . Australian archaeology. Open science Introduction Archaeology, like all scientific fields, advances through rigorous tests of previously published studies. When numerous investigations are performed by different re- searchers and demonstrate similar results, we hold these results to be a reasonable approximation of a true account of past human behavior.

  • Package 'Drake'
    Package ‘drake’ December 11, 2018 Title A Pipeline Toolkit for Reproducible Computation at Scale Description A general-purpose computational engine for data analysis, drake rebuilds intermediate data objects when their dependencies change, and it skips work when the results are already up to date. Not every execution starts from scratch, there is native support for parallel and distributed computing, and completed projects have tangible evidence that they are reproducible. Extensive documentation, from beginner-friendly tutorials to practical examples and more, is available at the reference website <https://ropensci.github.io/drake/> and the online manual <https://ropenscilabs.github.io/drake-manual/>.

  • Large-Scale Parallel Statistical Forecasting Computations in R
    Large-Scale Parallel Statistical Forecasting Computations in R Murray Stokely∗ Farzan Rohani∗ Eric Tassone∗ Abstract We demonstrate the utility of massively parallel computational infrastructure for statistical computing using the MapReduce paradigm for R. This framework allows users to write com- putations in a high-level language that are then broken up and distributed to worker tasks in Google datacenters. Results are collected in a scalable, distributed data store and returned to the interactive user session. We apply our approach to a forecasting application that fits a variety of models, prohibiting an analytical description of the statistical uncertainty associated with the overall forecast. To overcome this, we generate simulation-based uncer- tainty bands, which necessitates a large number of computationally intensive realizations. Our technique cut total run time by a factor of 300. Distributing the computation across many machines permits analysts to focus on statistical issues while answering questions that would be intractable without significant parallel computational infrastructure. We present real-world performance characteristics from our application to allow practitioners to better understand the nature of massively parallel statistical simulations in R. Key Words: Statistical Computing, R, forecasting, timeseries, parallelism 1. Introduction Large-scale statistical computing has become widespread at Internet companies in recent years, and the rapid growth of available data has increased the importance of scaling the tools for data analysis. Significant progress has been made in design- ing distributed systems to take advantage of massive clusters of shared machines for long-running batch jobs, but the development of higher-level abstractions and tools for interactive statistical analysis using this infrastructure has lagged.

  • Compiler and Runtime Techniques for Optimizing Dynamic Scripting Languages
    c 2015 by Haichuan Wang. All rights reserved. COMPILER AND RUNTIME TECHNIQUES FOR OPTIMIZING DYNAMIC SCRIPTING LANGUAGES BY HAICHUAN WANG DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Computer Science in the Graduate College of the University of Illinois at Urbana-Champaign, 2015 Urbana, Illinois Doctoral Committee: Professor David A. Padua, Chair, Director of Research Professor Vikram Adve Professor Wen-Mei W. Hwu Doctor Peng Wu, Huawei Abstract This thesis studies the compilation and runtime techniques to improve the performance of dynamic scripting languages using R programming language as a test case. The R programming language is a convenient system for statistical computing. In this era of big data, R is becoming increasingly popular as a powerful data analytics tool. But the performance of R limits its usage in a broader context. The thesis introduces a classification of R programming styles into Looping over data(Type I), Vector programming(Type II), and Glue codes(Type III), and identified the most serious overhead of R is mostly manifested in Type I R codes. It pro- poses techniques to improve the performance R. First, it uses interpreter level specialization to do object allocation removal and path length reduction, and evaluates its effectiveness for GNU R VM. The approach uses profiling to translate R byte-code into a specialized byte-code to improve running speed, and uses data representation specialization to reduce the memory allocation and usage. Secondly, it proposes a lightweight approach that reduces the interpretation overhead of R through vectorization of the widely used Apply class of operations in R.
