Geostatistics and Image Analysis (Prof. Edzer J. Pebesma): During this thematically broad seminar in 2008/09 I investigated R's abilities for handling large image data together with Hennig Bredel. See our report for details: PDF download.
R+OSGeo (R and open source for spatio-temporal geographic data): A block seminar during September 2009 held by Tomislav Hengl, Victor Olaya Ferrero and Edzer J. Pebesma. In the final project made an original contribution to the open source community by porting the Flow Map Layout algorithm by D. Phan to the free SEXTANTE algorithm library.
