The Southern Oscillation Index (SOI) is the difference in barometric
pressure at sea level between Tahiti and Darwin.  Monthly and annual SOI
data, for the years 1876-2011, are given.


datasets

various data sets used in additional exercises for
the book Maindonald, J.H. and Braun, W.J. (3rd edn 2010)
"Data Analysis and Graphics Using R", and for a
'Data Mining' course.  Note that a number of datasets
that were in earlier versions of this package have been
transferred to the DAAG package.
