It is one of the reasons why I am currently involved in a collaboration (among some others) on genome (or transposon) ecology by co-advising Brent Saylor with Ryan Gregory, and on anthropology in ecology by co-advising Ingrid Ng with Bob Jickling."Cross links show complex relationships between two or more distinct segments of the concept map"
And here is another cross link I was recently struck by: "Up and down the ladder of abstraction" by Bret Victor (no screen shot, because you have to explore the site in person) -
which I think is linked to "Engineering data analysis" by Hadley Wickham.
Both advocate an explicit visual tool to explore complicated and unexpected patterns between groups of variables. The domain specific visual language advocated by Hadley Wickham, I think, implicitly provides a model to obtain the different levels of abstractions necessary for moving up and down your data iteratively in R.
Would Hadley Wickham have Bret Victor in his RSS reader? If not, I think he should, because imagine what would happen if we put these two together in the same room.
