Coffee and Econometrics in the Morning: Avoiding Loops in R: An Example with Principal Minors

Want a Coffee and Econometrics Mug? Monday, July 18, 2011. Avoiding Loops in R: An Example with Principal Minors. Yesterday, I found myself wanting to compute a large subset of the second order principal minors of a matrix (diagonal-preserving minors; the ones for which the rows and columns kept are the same). Don't judge. Me for wanting to do this, and bear with me, there is a lesson about R programming here (mostly for me, read the comments for testing). And there's a lot of related theory. This is in R.

Coffee and Econometrics in the Morning: Recreational R: Simulating a Card Trick
http://novicemetrics.blogspot.com/2011/05/recreational-r-simulating-card-trick.html
Want a Coffee and Econometrics Mug? Monday, May 30, 2011. Recreational R: Simulating a Card Trick. In this post, I simulate an interesting card trick, which was described by a friend of mine named Xan. Here's Xan's description of the card trick. I put a deck of cards down face up on the table. Meanwhile you think of a secret number between 1 and 10 - for exposition let's say you pick 4. But I don't just stop on any card. I stop on your current special card. Which I'm not supposed to know. Here's the resu...

Graduate Grumblings: Epic road trip
http://graduategrumblings.blogspot.com/2015/07/epic-road-trip.html
Tuesday, July 07, 2015. We decided for Chris and Angela's wedding we would make an epic road trip to California. We would cross Iowa, Nebraska, Colorado, Utah, Nevada and finally stop when we got to the Bay Area. I didn't take any pictures in Nebraska. It is a subtler place the the rough crags of Colorado. We stayed with Rich for a couple of days before our next drive to Utah to visit the Cooks. Becca was in heaven talking to the lambs and cows. The bummer lamb her favorite thing ever. But it didn't last.

Coffee and Econometrics in the Morning: Splitting Vectors of Uneven Strings
http://novicemetrics.blogspot.com/2011/07/splitting-vectors-of-uneven-strings.html
Want a Coffee and Econometrics Mug? Friday, July 29, 2011. Splitting Vectors of Uneven Strings. Suppose you have a vector of names such that the first three words in the vector contain relevant information, but there is a bunch of extraneous stuff. For example,. Our goal is to collapse the first three words into one contiguous string (without the spaces) and we want to discard the extra words (because they're extraneous infromation). For a situation like this, my first thought is to use the strsplit().
