Interview Jeff Allen Trestle Technology #rstats #rshiny

Here is an interview with Jeff Allen who works with R and the new package Shiny in his technology startup. We featured his RGL Demo in our list of Shiny Demos- here


Ajay- Describe how you started using R. What are some of the benefits you noticed on moving to R?

Jeff- I began using R in an internship while working on my undergraduate degree. I was provided with some unformatted R code and asked to modularize the code then wrap it up into an R package for distribution alongside a publication.

To be honest, as a Computer Science student with training more heavily emphasizing the big high-level languages, R took some getting used to for me. It wasn’t until after I concluded that initial project and began using R to do my own data analysis that I began to realize its potential and value. It was the first scripting language which really made interactive use appealing to me — the experience of exploring a dataset in R was unlike anything Continue reading “Interview Jeff Allen Trestle Technology #rstats #rshiny”

Rcpp Workshop in San Francisco Oct 8th

 Rcpp Workshop in San Francisco  Oct 8th 

Following the successful one-day master class on Rcpp preceding this year’s R/Finance conference, a full-day master class on Rcpp and related topics which will be held on Saturday, October 8, in San Francisco.

Join Dirk Eddelbuettel for six hours of detailed and hands-on instructions and discussions aroundRcppinline,  RInsideRcppArmadilloRcppGSLRcppEigen and other packages—in an intimate small-group setting.

The full-day format allows combining an introductory morning session with a more advanced afternoon session while leaving room for sufficient breaks. We plan on having about six hours of instructions, a one-hour lunch break and two half-hour coffee breaks (and lunch and refreshments will be provided).

Morning session: “A Hands-on Introduction to R and C++”

The morning session will provide a practical introduction to the Rcpp package (and other related packages).  The focus will be on simple and straightforward applications of Rcpp in order to extend R and/or to significantly accelerate the execution of simple functions.

The tutorial will cover the inline package which permits embedding of self-contained C, C++ or FORTRAN code in R scripts. We will also discuss  RInside, to easily embed the R engine code in C++ applications, as well as standard Rcpp extension packages such as RcppArmadillo and RcppEigen for linear algebra (via highly expressive templated C++ libraries) and RcppGSL.

Afternoon session: “Advanced R and C++ Topics”

The afternoon tutorial will provide a hands-on introduction to more advanced Rcpp features. It will cover topics such as writing packages that use Rcpp, how Rcpp modules and the new R ReferenceClasses interact, and how Rcpp sugar lets us write C++ code that is often as expressive as R code. Another possible topic, time permitting, may be writing glue code to extend Rcpp to other C++ projects.

We also expect to leave some time to discuss problems brought by the class participants.
