Adding external images to plots - First RLadies Oslo meetup!

A message from the "sister-meetup" RLadies-Oslo:

RLadies-Oslo is a recently initiated chapter of RLadies Global, a community of female R-users dedicated to sharing and contributing to the use of R-statistical software.

RLadies-Oslo will be hosting their first meetup on April 23rd at Teknologihuset, and welcome those who are interested in attending.

In this first meetup, Athanasia Monika Mowinckel will be talking about how to add external images to plots, to help with data visualization. After the talk, there will be time for questions and mingling.


Future meetups are open to anyone wishing to present what they are working on. It does not matter your skill level, just that you want to share how you work. Someone might benefit from your approach, or others might give you pointers on how to improve your work. #RLadies Oslo want this to be an open and including arena, so everyone can learn from each other. Any questions can be sent to Monika directly, or through the meetup (see the link above).
