R workshop XVII: Basic

Presenter: Katya N. Vasilaky, PhD.

Bio: Katya Vasilaky is a postdoctoral research fellow at Columbia University's Earth Institute working in both economics and bayesian statistics. She has been working with data and statistics for the last ten years, primarily in developing countries from East Africa to India to Asia for the last 10 years. She was also the VP of Research for a tech startup,, in Washington DC.

Overview: This workshop will be a brief intro to using R for data analysis for the beginner. Some familiarity with data and statistics will be helpful. This will not be a comprehensive introduction to R. Rather, it will be a short introduction to using R for simple analysis. We'll use a sample dataset to munge and manipulate into a format for running statistics and graphs. In that process we'll cover some common R functions that an analyst would most commonly use: subset, rep, split, dates, plyr package, merges/joins, csv, if/else statement, and a for/while loop.  

$5 is collected for dinner and to cover costs. 

Meetup has been having some difficulties with paypal. If you registered, but don't see your rsvp listed,  send Margot an email at [masked] with a confirmation of your payment and she will update your rsvp. 

**We always look for space sponsorship. Please contact me if you have any space available. Your colleagues and friends are welcome to join us, too.**

    Thank you all for making this such a successful event! The turnout was amazing and I hope you learned a lot! As promised, I'm posting some announcements. First, The NYC Data Science Academy has a pair of 5 week intensives coming up this weekend, check them out here: Next week we're starting Data Science Wednesdays at Alley NYC (500 7th Ave, Manhattan on the 17th Floor). We're hosting it from 6 to 8 pm. It's an office hours kind of environment - bring a question or problem you're working on and there will be somebody to help. Or, if you're the expert, feel free to stick around and help others out. It also coincides with Alley's happy hour, so there will be beer sponsored by them! You can RSVP here:

    Finally, we have *two* R meetups next week, on the 8th and 10th, covering Machine Learning and Elastic Net/Lasso/Ridge-Regression. You can RSVP right here on Meetup!

    Thanks Katya. The two R coding files are comprehensive enough to serve as my cheat sheet. I will review and retrieve the them frequently....

    Looking forward to this evening's workshop! So everyone knows the level of this workshop: we'll be covering the very basics in R, and then running through a short script working with data.

      If possible, can you use Mac's quick time's screen recording to capture your screen? It will be super helpful for people who want to learn it later.
