R - Birth Month by Gender - How R is used at Microsoft




Birth Month by Gender Based on some feedback to a previous post I normalised the birth counts by the (average) number of days in each month. As pointed out by a reader, the results indicate a gradual increase in the number of conceptions during (northern hemisphere) Autumn and Winter, roughly up to the end of December. Normalising the data to give births per day also shifts the peak from August to September. LINK. How R is used at Microsoft At the useR! conference last month, I was pleased to be able to give a couple of talks about the ways that Microsoft is using and integrating R. In my first talk,Hear, See, Move, I shared how data scientists at Microsoft are working to help the disabled: LINK. GREA: The RStudio Add-In to read ALL the data into R! Have you also been overburdened by the vast selection of R packages to read different filetypes into R? Do you sometimes just want to get that . csv file up and running in your environment, but forgot about all those endless read. table() options? LINK

R - Data frame columns as arguments to dplyr functions




Data frame columns as arguments to dplyr functions Suppose that you would like to create a function which does a series of computations on a data frame. You would like to pass a column as this function’s argument.  LINK. New Release of partools Package My new release of partools is now on CRAN. The package is aimed at doing parallel data science in what I call an “un-MapReduce” manner. It takes the point of view that MapReduce-based frameworks such as Hadoop and Spark are fine for the types of applications their designers had in mind, namely rather simple SQL actions, but have fundamental handicaps that prevent them from performing well on many, if not most, of the types of computation that typical users need for large data sets and/or highly compute-bound applications. The distributed file/object nature of those MapReduce systems is retained, but the confining MapReduce computational paradigm is avoided.  LINK. Data Science Boot Camp completed at Ryerson University I am pleased to update you on theData Science Boot Camp we ran at the Ted Rogers School of Management at Ryerson University in Toronto in collaboration with IBM’swww. BigDataUniversity. com. The 9-week long Boot Camp concluded on July 15.  LINK.

R blogeri, SQL Server, Power BI, and R




SQL Server, Power BI, and R SQL Server 2016 has reached general availability recently and one of the top new capabilities it features is SQL Server R Services —  advanced analytics in-database with the R language.    R has also been integrated into Power BI, allowing you to create fully integrated visualizations with the power of the R language.   In this blog post I will show an example using R in SQL Server to create a model and  batch score testing data, then use Power BI Desktop to create visualizations of the scored data. An Introoduction to Portfolio Component Conditional Value At Risk This post will introduce component conditional value at risk mechanics found in PerformanceAnalytics from a paper written by Brian Peterson, Kris Boudt, and Peter Carl. This is a mechanism that is an easy-to-call mechanism for computing component expected shortfall in asset returns as they apply to a portfolio. While the exact mechanics are fairly complex, the upside is that the running time is nearly instantaneous, and this method is a solid tool for including in asset allocation analysis.
