Our June meetup Our June meetup was about cleaning data using R. Data cleaning is the process of preparing your data for analysis; ensuring that it is technically correct and in the desired format. Data cleaning can often be more time-consuming than the actual analysis! We were live tweeting the event! Check out some tweets below. Introduction Darina and Katerina provided an introduction to data cleaning, with a focus on the process of ensuring the data is technically correct.


Our May Event! The May R-Ladies meetup took place on May 16, 2018 at Drexel’s LeBow School of Business. Thanks for hosting us again, Drexel, and thanks to our sponsors Datacamp and the R consortium! Our topic for May was version control using the popular resources Git and GitHub, and we focused on integrating version control with R. Intro Darina and I started with an example to illustrate the utility of version control in collaborating on a document or project over time.


Our April Event! The April R-Ladies meetup was held on April 19th at Drexel. Thanks again to Drexel for hosting us and to DataCamp and the R consortium for sponsoring us! Our topic was an introduction to text mining in R using the first two chapters of “Text Mining with R” by fellow R-Lady(!) Julia Silge and David Robinson. There was a great group - including some new faces! Amy took us through the key concepts of the chapter and then we broke into groups to do some exercises together.


Why do a new member survey? One of the goals of R-Ladies Philly is for the group to be focused on the needs and interests of its members. With this goal in mind, we created a survey to query members about meeting logistics and R experience level. This survey also provided a mechanism to collect emails in order to invite new members to our Slack channel. If you want to join us and fill out the survey, you can find it here: http://bit.


Hello and thank you for visiting our brand-new R-Ladies Philly blog! For our first post, we are introducing the founding principles of our chapter and our goals moving forward. With that in mind, if you R ready, here we go! As you may already know, R-Ladies Philly is a chapter of the broader R-Ladies global organization. R-Ladies global seeks to promote gender diversity in the coding community by providing a collaborative network of R learners, mentors, and leaders.

Karla Fettich, PhD

Karla works as Head of Algorithm Development at Orchestrall, where she leads behavioral data analytics efforts and predictive model development for healthcare IT innovation. Currently, Karla uses R to create a new product that uses machine learning and predictive analytics to serve as a companion to nurse aides in their care for the elderly. Originally from Romania, Karla completed her B.A. in social and cognitive psychology at Jacobs University Bremen in Germany, her M.A. in social sciences at the University of Chicago and her Ph.D. in psychology and neuroscience at Temple University in Philadelphia.

Amy Goodwin Davies, PhD:

Amy is a linguist-by-training and aspiring data scientist. In particular, she is excited about developing her skills in text mining and natural language processing. Amy completed her PhD in Linguistics at the University of Pennsylvania, where her research focused on the grammatical representations involved with word recognition. Amy is originally from the UK. Before moving to Philadelphia in 2012, she completed her undergraduate studies at the University of Edinburgh.

Katerina Placek, MSc

Katerina is a PhD candidate in Neuroscience at the University of Pennsylvania. She uses R in her research to statistically evaluate genetic risk factors for frontotemporal disease in amyotrophic lateral sclerosis and to visualize results. Katerina started an R-Learning group in her lab at the University of Pennsylvania, and was recruited by Alice to help start R-Ladies Philly!

Alice Walsh, PhD

Alice is a computational biologist who works in pharmaceutical drug development and has lived in the Philadelphia area for the last ten years. She uses R to transform biomarker data from patients into useful insights that can help doctors make better decisions. Alice was inspired to start an R-Ladies chapter in Philadelphia after seeing a video of another R-Ladies meetup online.
