R-Ladies NYC are excited to be hosting an evening of lightning talks on Wednesday June 19! We held this event last year and it was a tremendous success, so we are really excited about the event this year! Lighting talks are five minute talks. You can talk about anything R, Tech, and/or Data Science related. Looking for ideas? How about talking about a cool package you found, how you use R in your company, a favorite learning resource, your journey into Data Science, or a side project you’ve been working on?

The R-Ladies NYC call for a hex sticker design produced three creative and unique submissions. We would like to thank Ayanthi Gunawardana, Kat Hoffman, and Ludmila Janda for their involvement with the R-Ladies NYC community and time spent crafting their designs! Below, each of these R-Ladies shares her inspiration behind her design: Ayanthi Gunawardana: My goal was the keep the logo and colors as simple as possible to ensure it could be scaled to any size.


Thank you so much to Anisha BharathSingh, who originally wrote this post for her blog, found here. We are reposting her post with her consent. If you are an R-Lady interested in writing a blog post or cross-posting a blog post on your own blog, please let us know (via email or via DM on twitter @RLadiesNYC)! On Thursday, May 23, I attended my first R-Ladies NYC meetup! R-Ladies NYC is an organization that promotes gender diversity amongst the R community by organizing a series of events (including this meetup) to support women who want to learn R or want to share their experiences as R programmers.


The New York R conference attracts a diverse yet technical audience which means the bar is high for all invited speakers. This year, over half the speakers were women, including several R-Ladies NYC members. It was such a fun and good experience that we decided to collaborate and write a blog post to encourage others to speak at conferences and provide some tips. Speakers: Ludmila Janda, Emily Robinson, Emily Dodwell, Gabriela Hempfling, Elizabeth Sweeny, Soumya Kalra, Brooke Watson, Amanda Dobbyn, Letisha Smith


The 2018 New York R Conference was my first ever R conference, and it was great. I’ll write here about my experience, with links to resources from the widely varying talks. First and foremost, I want to thank RLadiesNYC for the scholarship which allowed me to attend the conference. As a self-taught R newbie and incoming grad student, I greatly benefitted from attending this conference, and I so appreciate the opportunity from this great group!
