I think transition plot is perfect but I can't get how does it work?
My data frame is called (Cimad) and my variables are EMPLOIPRE (origin) and EMPLOIFR (destination). Both are factors, the first count 20 levels, the second 15 levels (is it a problem, do I have to make them all match?) and I have 400 observations.
I hope you'll be able to help me because I am completely lost ! Thank you in advance less

x <- rnorm(100)
eps <- rnorm(100,0,.2)
qplot(x,3*x+eps)
qplot(x,2*x+eps)
Do I need to put them in the same data.frame?
qplot(displ, hwy, data=mpg, facets = . ~ year) + geom_smooth()

If it's something like a binary search I just imagine a bunch of boxes in a row, and throwing half of them out each time. Is there something more powerful that will let us grok something as abstract as an algorithm/data structure?Clarification: I'm looking for something a little more general. Example: in order to visualize time - some people use a clock in there head but thats slow, whereas a more natural feel would be a globe and if you are trying to get a 'feel' for how an algorithm works you can imagine two objects moving in different directions on that globe.

Whether it's Number (decimal), Number (whole), String, Boolean, etc. A few questions about this:
1) Has Tableau ever misclassified one (or more) columns of your data with their automatic labeling? If so, would you please give details?
2) Do you feel that these data type options can be improved? For example, Tableau doesn't seem to be distinguishing between unordered categorical data and ordinal data.
Thanks!

Is there some place in Tableau where I can view/edit/reset full list of aliases?

The reports will mix tables and charts (mainly sparkline and bullet graphs created with ggplot2). Think Stephen Few/Perceptual Edge style dashboards, such as:
but applied to web analytics.
Any suggestions on what packages to use creating these dashboard reports?
My first intuition is to use R markdown and knitr, but perhaps you've found a better solution. I can't seem to find rich examples of dashboards generated from R. less

I just need a tool I can quickly point at a database and it'll show basic table structure and field types, etc. Nothing too advanced or crazy.
