Secure Package Downloads for R. RStudio Support June 18, 2019 20:40. If you are using Packrat to manage your packages within projects, you may also see warnings when switching to an older project. In that case you'll need to update the repository for that project following the directions below. RStudio is an active member of the R community. We believe free and open source data analysis software is a foundation for innovative and important work in science, education, and industry. The many customers who value our professional software capabilities help us contribute to this community. Visit our Customer Stories page to learn more. R is a system for statistical computation and graphics. It consists of a language plus a run-time environment with graphics, a debugger, access to certain system functions, and the ability to run.

This collection of samples gets you started on R, R Tools for Visual Studio (RTVS), and Microsoft Machine Learning Server:

R-Net is a project and is an initiative. R-Net as a project involves the development of a database which will allow the exchange of ideas and boost peer to peer collaboration to improve the city living standards; the recruiting, organization and mobiliza: Size: 2.0 MB License: Freeware.

Prior to R 3.2.3 the 'wininet' method used active mode: nowadays it first tries passive and then active. Good practice.

1. Download the samples zip file and extract to a folder of your choice.

2. Open examples/Examples.sln to see two folders in the project:

   • A First Look at R gives a gentle introduction for newcomers to R.
   • MRS and Machine Learning gives examples of how to use R and Microsoft Machine Learning Server for machine learning.

A First Look at R

This sample provides an in-depth introduction to R through the extensive comments in two source files. For the best experience, place the cursor at the top of the file and press Ctrl+Enter to send the code line-by-lie to the R Interactive window. (Lines that install packages might take a minute or two to complete.)

• 1-Getting Started with R.R covers many R fundamentals including using packages, loading and analyzing data, and plotting.

• 2-Introduction to ggplot2.R introduces the ggplot2 graphic package known for its visually appealing plots and simple syntax. This example visualizes earthquake data from Fiji.

Microsoft Machine Learning Server and Machine Learning

This collection of examples shows how to use R to create machine learning models and to take advantage of Microsoft Machine Learning Server.

As with all examples, open the file, place the cursor at the top, and then step through the code line by line with Ctrl+Enter. The markdown files in each folder also contain additional details.

• Benchmarks runs a number of intensive, parallel linear algebra computations to show the performance gains that are possible through the use of Microsoft R Open and the Intel Math Kernel Library (MKL). With simulated data, the benchmarks specifically compare matrix calculations on one thread versus two.

• Bike_Rental_Estimation_with_MRS creates a demand prediction model for bike rentals based on a historical data set, using Microsoft ML Server.

• Data_Exploration contains three scripts:

  • Import Data from URL.R shows how to load a URL-identified data file into R.

  • Import Data from URL to xdf.R shows how to load a URL-identified data file into Microsoft ML Server as an xdf.

  • Using ggplot2.R is an extension of the A First Look at R/2-Introduction to ggplot2.R sample, giving a more extensive tour of ggplot2's functionality including interactive 3D plotting.

• Datasets contains three .csv files used by other samples

• Flight_Delays_Prediction_with_R and Flight_Delays_Prediction_with_MRS shows how to predict flight delays using R, machine learning, and historical on-time performance and weather data.

• Machine learning contains three samples for learning to predict flight delays, housing prices, and bike rentals. Together, these samples demonstrate the application of R and Microsoft ML Server to real-world problems. They also show you how to use several popular machine learning models and deploy them as an Azure Web Service using an Azure Machine Learning workspace.

• R_MRO_MRS_Comparison is a six-part comparison that shows the similarities and differences of R, Microsoft R Open and Microsoft ML Server with commands, syntax, constructs, and performance.

What's special about Microsoft R Open and Microsoft ML Server?

R Project Download Mac

Microsoft R Open, Microsoft's distribution of R, is different from CRAN R in two important ways:

1. Better computation performance when used with the Intel Math Kernel Libraries. The libraries are available as a free download from Microsoft for use with Microsoft R Open.

2. Reproducible R Toolkit ensures that the libraries you used to build your R program are always available to others that want to reproduce your work.

Microsoft ML Server (MLS) is an extension of R that allows you to handle more data and handle it faster. It gives R two powerful capabilities:

1. Larger data sets without RAM limitations. ML Server can process out-of-memory data from a variety of sources including Hadoop clusters, databases, and data warehouses.

2. Parallel, multi-core processing. MLS can efficiently distribute computation across all the computational resources it has available. On your personal workstation or a remote cluster, MLS gets an answer faster.

The following comparison shows that MLS and MRO with MKL have significantly better computation performance related to certain matrix calculation than R and MRO without MKL. Simulated data is used in this calculation:

For a technical comparison of R with MRO and MLS, check out Lixun Zhang's detailed discussion on the topic.

The following figure then compares elapsed time in seconds used in building Logistic Regression models to predict flight delays greater than 15 minutes. Elapsed time used in CRAN R increases dramatically when increasing a small number of rows, while MLS increases only by approximately two times.
