comment Mapping a function of the form matrix[[row,column1;;column2]] over a list
Cases[] seems, to me, to be a function with an especially high level of abstraction. I suppose that is because it works with the structure of things rather than the values of things. I'm always pleased when I can do something this way. So, very nice.

I'm happy to see that you CAN use MapThread.

Yes! It does work. I've never used @@@ before. Apply on steroids. Simple and beautiful. Thanks.

@kguler It doesn't seem to, but it seems like it should. I'm going to work with a little.

comment Point-like function but with diamond instead of circle
How does the syntax [xy : {x_, y_} : {0, 0} work? Is it like a chain of defaults?

I've seen your icon, but it hadn't registered as an example of what I wanted to do. Did you use translate?

@Szabolcs Yet another function I didn't know about. Translate seems pretty handy. It seems like it should work.

comment Mathematica 10 'Formatting Notebook Contents'
I have the same problem, but only on my 64 bit Windows 8 (very fast, lots of memory) laptop. Not on my not so fast Windows 7 desktop.

comment Using KalmanFilter or KalmanEstimator
Is using a mean filter considered the best way to get the trend if you don't know anything else? Is it standard to use this approach to difference out the noise? Finally, are there standard methods for choosing a model for the noise?
