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 1876-2008, are given.

datasets

various data sets used in additonal exercises for the book
        Maindonald, J.H. and Braun, W.J. (2nd edn 2007) "Data Analysis
        and Graphics Using R", and for a 'Data Mining' course.  Note
        especially the datasets \code{nassCDS} (airbag and other
        influences on US vehicle accident outcomes: 1997-2002),
        \code{cricketer} (handedness, British first class cricketers
        born 1840-1960 whose handedness could be determined),
        \code{nswdemo} and related datasets (US Labor Training
        Evaluation Data), \code{rockArt} (multivariate binary data on
        Pacific rock art), \code{hotspots} (ages and distance from
        Kilauea of larval hotspots; c.f. also \code{hotspots2006}),
        \code{nihills} (record times for Northern Ireland mountain
        races), \code{worldRecords} (record times for track and road
        races), \code{progression} (progression of record times for
        track races), \code{edcT} and \code{edcCO2} (temperature and
        CO2 estimates from the EPICA Dome C ice core, covering 0 to 800
        kyr BP), \code{grog} (Australian and NZ liquor consumption
        patterns, 1998-2006), and \code{bomregions} (historical
