discussion on how we can use statistical methods to measure and improve the efficacy of http://freeCodeCamp.com
The cover is a nice tribute to Hal.
The examples in this book were written for and tested with R Version 2.15.3
Pretty old though. First published 2013, but was written may be much earlier

Taking a look at Advanced R too, @zcassini. I think they are letting out mostly books that are relatively outdated, but even if the versions have been replaced by better ones most of the techniques are still up to date.
@gayathry2612 I did some kaggling before coming to FCC. Really good. If you want to go ML, that is one of the best places indeed. Go to previous challenges and read the fora when public, and even try to solve previous problems even if closed if you have time.
We are currently working on data coming from the first FCC Survey (15,000 records, 40 questions). Join us! @SamAI-Software is very active in that area and he is organising the info. You can see @SamAI-Software's analyses if you scroll up this page. We are discussing the results and giving tips for our visualizations. Historically we have been using python for the analyses in this room, but for the FCC Survey we are using R (@erictleung's code).
The objective of this exercise is to bring those results as d3.js visualizations. You can see @krisgesling's map for an example. If you don't know d3.js yet, you could at least make some analyses on the data that could be make as viz later on.
The room is open to all the topics and discussions even though the focus data is usually FCC data.
I have also prepared a (WIP) page of what has happened in this room since its foundation if you are curious:
Hope you will all enjoy!
/all A huge round of :clap: for @erictleung for merging and cleaning the dataset, and everyone else who helped with this process.
The full, cleaned dataset is now available here: https://github.com/FreeCodeCamp/2016-new-coder-survey/tree/master/clean-data
Please use this for building your visualizations.
To my knowledge, there's nothing else that we're waiting on, so let's get started answering these questions with D3 data visualizations :shipit: https://github.com/FreeCodeCamp/2016-new-coder-survey/issues?q=is%3Aissue+is%3Aopen+label%3Aquestion
Good luck, and if you have any questions, this chatroom is the best place to ask :)

@gitdek Great! There are no plans for a expansion in the short term. There is a proposal for an annual survey, 2016 is the first one.
Have a look! There is some interesting stuff in that dataset... Check the repo and also ask @SamAI-Software.

@gitdek the records are anonymous already.
Not only FCC members I am afraid, but you can analyse data for the first 2 weeks to get the best of FCC members, who were the main surveyed during the first stages of the project. Maybe... although I would recommend not to try that extrapolation and just concentrate on survey results.
About how many months have you been programming for?
In a different direction, not because of politics but just check the VIZ for this one, as example and possible inspiration for your your projects?
