     The 'varespec' data frame has 24 rows and 44 columns.  Columns are
     estimated cover values of 44 species.  The variable names are
     formed from the scientific names, and are self explanatory for
     anybody familiar with the vegetation type. The 'varechem' data
     frame has 24 rows and 14 columns, giving the soil characteristics
     of the very same sites as in the 'varespec' data frame. The
     chemical measurements have obvious names. 'Baresoil' gives the
     estimated cover of bare soil, 'Humpdepth' the thickness of the
     humus layer.
