Hadley Wickham: First the slides for Hadley’s talk are on his github page. Hadley started his talk off with a short demo
showing how interactive graphics could allow you to learn about your data. He has a clever dataset of 3d data points and
these show no apparent pattern when viewed along any two axes. However when viewed from the correct angle we
discover that there is a very distinct spiral pattern in the data this provides
a nice aha moment in his talk. Next Hadley
discussed the history of interactive graphics in R splitting them into 3
categories 1) those written in lower level languages, 2) those hacking existing
R plotting functions, and 3) and browser based solutions. Many of the packages that he showed are not
very realistic for everyday use or for investing a lot of time since they are
no longer being actively developed.
Perhaps the most interesting part of Hadley’s talk was his
discussion and demonstration of ggvis this is Hadley’s package that he
envisions eventually replacing ggplot2.
His goal is to continue to work on this and perhaps sometime in 2016
have it to the point that anything you could do in ggplot2 you can do in
ggvis. The upside of this is that if you
are already comfortable with ggplot2 you will have no trouble transitioning
into ggvis. Hadley is using the same type
of grammer based approach to building up more complex graphs from simpler
elements.
Winston Chang gave a much shorter talk but illustrated some
of the new interactive developments in Shiny.
Despite my use of Shiny I was actually completely unaware of this
development. Winston has added some nice
examples on the Shiny articles page (bottom of right column).
