Join us on March 17 at 6pm as we explore how to build interactive reports using RMarkdown and Shiny. We will walk through an example of an interactive bioinformatic report that allows users to investigate how parameter changes affect results.

Hope to see you there!

#rstats
RMarkdown and Shiny can be combined to generate interactive documents and analysis reports. For this meetup, I will demonstrate the use of R to analyze gene expression (RNA-seq) via the edgeR package from Bioconductor. By combining RMarkdown/Shiny with the edgeR package, we will create an interactive report that will allow the user to explore how changing parameters will affect analysis results and possibly the biological conclusions. We will me...

"Where the market is broad and there are many alternatives, you had better cooperate.  If you choose the noncooperative solution, you may find you have no one to noncooperate with."

Join me on February 17th at 6pm to learn how to use xts for high performance time series manipulation in #rstats!
The xts package makes it easier to handle time series data by combining the simplicity of the zoo class with an index that must be a time-based class.  This allows for easy subsetting via ISO-8601 style strings (e.g. "[masked]:40/[masked]:40"), fast time-based merges, and easy conversion to/from other time series classes. This talk will discuss the rationale behind xts' design, a short overview of the class implementation, discussion of R's main ...
