Managing a statistical analysis project – guidelines and best practices

In the past two years, a growing community of R users (and statisticians in general) have been participating in two major Question-and-Answer websites:

  1. The R tag page on Stackoverflow, and

Tips for the R beginner (a 5 page overview)

In this post I publish a PDF document titled “A collection of tips for R in Finance”.
It is a basic 5 page introduction to R in finances by Arnaud Amsellem (linked in profile).

The article offers tips related to the following points:

  • Code Editor
  • Organizing R code
  • Update packages
  • Getting external data into R
  • Communicating with external applications
  • Optimizing R code

Update: as some readers have noted to me (by e-mail, and by commenting), this document touches very lightly on the topic of “finances” in R. I therefore decided to update the title from “R in finance – some tips for beginners”, to it’s current form.

Lastly: if you (a reader of this blog) feel you have an article (“post”) to contribute, but don’t feel like starting your own blog, feel welcome to contact me, and I’ll be glad to post what you have to say on my blog (and subsequently, also on R bloggers).
