RStudy Recap/Reminder 7/7

[Joe]

Hi All,

Last week, we worked through some approaches for using the plyr
package to summarize and aggregate data amongst other things. The
notes from last week are here:

The two most useful concrete examples I gave (I think) are a plyr
implementation for vowel normalization, and a method for fitting a
logistic regression to the data from every speaker from a sample.

We mentioned bringing in data sets to workshop next week, but I think
we should probably go over reshaping our data into useful formats
first. The format of this week will involve mostly concrete examples
of data reshaping. The data sets I intend to use are on US casualties
in Iraq and Afghanistan, international data on the gender gap in
literacy, education, income and life expectancy, and the Peterson and
Barney data set.
