The Azure Data Lake store is an Apache Hadoop file system compatible with HDFS, hosted and managed in the Azure Cloud. You can store and access the data within directly via the API, by connecting the filesystem directly to Azure HDInsight services, or via HDFS-compatible open-source applications. And for data science applications, you can also access the data directly from R, as this tutorial explains. To interface with Azure Data Lake, you’ll use U-SQL, a SQL-like language extensible using C#. The R Extensions for U-SQL allow you to reference an R script from a U-SQL statement, and pass data from Data Lake into the R Script. There’s a 500Mb limit for the data passed to R, but the basic idea is that you perform the main data munging tasks in U-SQL, and then pass the prepared data to R for analysis. With this…

I’m delighted to announce the release of version 1.0.0 of the dplyrXdf package. dplyrXdf began as a simple (relatively speaking) backend to dplyr for Microsoft Machine Learning Server/Microsoft R Server’s Xdf file format, but has now become a broader suite of tools to ease working with Xdf files. This update to dplyrXdf brings the following new features: Support for the new tidyeval framework that powers the current release of dplyr Support for Spark and Hadoop clusters, including integration with the sparklyr package to process Hive tables in Spark Integration with dplyr to process SQL Server tables in-database Simplified handling of parallel processing for grouped data Several utility functions for Xdf and file management Workarounds for various glitches and unexpected behaviour in MRS and dplyr Spark, Hadoop and HDFS New in version 1.0.0 of dplyrXdf is support for Xdf files and datasets stored…
