My data source originate from the OpenStreetMap project and was...

Examples for sjPlotting functions, including correlations and proportional tables with ggplot #rstats

Sometimes people ask me how the examples of my plotting functions I show here can be reproduced without having a SPSS data set (or at least, without having the data set I use because it’s not public yet). So I … Weiterlesen →

big geo-data visualisations

Spotting international conflict is very easy with the GDELT data set, combined with ggplot and R. The simple gif above shows snapshots of Russian/Soviet activity from January 1980 and January 2000. I think it also illustrates how Russia nowadays looks more to the east and the South than during the Cold War. The trend, though...

Mathematical abstraction and the robustness to assumptions

I’ve been showing my new favourite toys to just about anyone foolish enough to actually engage me in conversation. I described how my shiny new set of non-transitive dice work here, complete with a map showing all the relevant probabilities.

Processing ABI .fsa files in R, part 1.

I’ve been working on a lot of AFLP data this winter. I’d really like to be able to do all the analysis in R, for a few reasons.
