Querying and plotting linked data with R

Aalto has recently introduced (in Finnish) part of its data as open linked data.

The visualization playground offers some sample queries, and a nice and easy way of visualizing results with Google Charts Tools.

Lately, I have been practising the R programming language, so of course I wanted to try my (still small) muscles a little with this data as well. Thanks to the SPARQL client R package, part I of the tutorial of how to use it, friendly R bloggers, and the R graphics package, I produced a line plot that combines some statistics of Aalto publications since 1992. The same query is included in the visualization playground. The R code is there, and the plot here.
