R Users Discussion Group Meeting

Date: 16 January 2018
Time: 16:00 - 17:30
Location: Wageningen Campus, C0097 Atlas Building

The R Users Meeting is a monthly meeting for people working with R. PhD and MSc students, as well as staff members, both beginners as well as advanced R users are welcome. The meeting offers an opportunity to help each other with specific questions and exchange ideas. In each meeting a specific topic is discussed by demonstrating and discussing examples of R functions and example data. The second part of each meeting is reserved for short questions on R codes and offers opportunity to get advice on your R code and how to fix or improve it. The meetings are hands-on, so please try to run the code and prepare your questions prior to the meeting. Also, bring your laptop to the meeting. New group members are welcome and are kindly asked to contact us.

There is also an online meeting place where the participants can share problems and experiences additional to the monthly meeings: In the text you will find links to a few R scripts, R learning resources, a schedule of upcoming meetings, and the issue section where you can discuss your problems. You can visit everything; however to post or answer an issue, you have to create an account and log in.

Upcoming meetings

  • 16 January 2018: Johannes Kruisselbrink (Biometris): C++ code from R using Rcpp

Past meetings

  • 5 December 2017: R-Users Sinterklaas meeting.
    We will do some coding exercises to learn from each other.
    Homework: Prepare 1 basic (level Fibonacci numbers) and 1 advanced (level quick-sort algorithm) coding exercise. They can be very specific to your field, but you need to be able to explain them, so everybody can solve them. You can also include plotting (e.g. how to plot a dataset in a certain way).
    Reward: We will provide some Kruidnoten and drinks!
  • 7 November 2017: Making presentations in Rstudio: my (good/bad) experiences with IOSLIDES.
  • 3 October 2017: The Good, the Bad and the Ugly
  • 14 June 2017
  • 17 May 2017: An introduction to parallel programming with R12 April 2017: ggplot2 and other tools
  • 15 February 2017: Topic: not sure yet, but perhaps basic descriptive statistics in R. (CANCELLED)
  • 25 January 2017: Benjamin Brede (PhD candidate, Laboratory of Geo-information Science and Remote Sensing): "Raster processing with R: Reading, writing, manipulating, analyzing and modeling of gridded spatial data."
    It concerns the R-packages ‘raster’ and ‘gdalUtils’; Level: advanced
  • 14 December 2016: Ron Wehrens (Biometris) will talk about the Lattice plotting system and about good plotting habits. So: plotting in R! Level indication: somewhere between basic and intermediate
  • 16 November 2016: Vincent Garin, PhD candidate at Biometris: “Data structure and good practises in R”
