As New Yorkers do all we can to stay well in the times of coronavirus, all of our routines have changed. For some of us, this may mean more time devoted to strengthening our data skills. If this is you, here is a collection of resources that can get you up and running with learning a new skill in R. These were originally compiled for the R-Ladies NYC Code-llaboration Hangout back in January, and are organized by topic: Tidy Tuesday, Building a Package, Building a Website, Time Series Analysis and Everything Else.


R-Ladies NYC is proud and excited that one of our members, Emily Robinson, is co-authoring a book with a fellow R-lady, Jacqueline Nolis! The book, Build a Career in Data Science, is available for pre-order, which comes with online access to all currently available chapters (1-9) access to the rest of the chapters as they come out. This book is a practical guide to preparing for, finding, and excelling in a data science role.


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.
