Function of the day

Construct the path to a file from components in a platform-independent way.

Package of the day

This package implements a data structure similar to hashes in Perl and dictionaries in Python but with a purposefully R flavor. For objects of appreciable size, access using hashes outperforms native named lists and vectors.

Question of the day

On general request, a community wiki on producing latex tables in R. In this post I'll give an overview of the most commonly used packages and blogs with code for producing latex tables from less straight-forward objects. Please feel free to add any I missed, and/or give tips, hints and little tricks on how to produce nicely formatted latex tables with R.

Interesting to see this union of modern dance and computer imagery: It's not clear whether this is just pre-recorded graphics combined with well-timed choreography, or if the images are actually reacting to the dancer's movements. I suspect the former in this case (filmed in 2014), but recent advances in real-time motion detection should make true reactivity between dancers and the virtual environment possible. I hope to see something like that on stage someday soon.
