Make sure you didn't miss anything with this list of the Best of the Week in the Big Data Zone (November 07 - November 14). Here they are, in order of popularity:

1. Learn R: Hello World with R

  • This article represents some of the basic concepts you need to understand in order to write a Hello world using the R programming language.

2. How well does sample range estimate range?

  • I’ve been doing some work with Focused Objective lately, and today the following question came up in our discussion. If you’re sampling from a uniform distribution, how many samples do you need before your sample range has an even chance of covering 90% of the population range?

3. Extracting Datasets from Excel Files in a Zipped Folder

  • The title of the post is a bit long, but that’s the problem I was facing this morning: importing datasets from files, online. I mean, it was not a “problem”, more a challenge (I should be able to do it in R, directly)

4. Using R: R Class for Wildfire Scientists

  • Mazama Science has just finished creating class materials on using R for the AirFire team at the USFS Pacific Wildland Fire Sciences Lab in Seattle, Washington. Autodidacts new to R should take about 20-30 hrs to complete the course.

5. R: Converting a named vector to a data frame

  • I’ve been playing around with igraph’spage rank function to see who the most central nodes in the London NoSQL scene are and I wanted to put the result in a data frame to make the data easier to work with.
