     'structure' returns the given object with further  attributes set.

     structure(.Data, ...)

_A_r_g_u_m_e_n_t_s:

   .Data: an object which will have various attributes attached to it.

     ...: attributes, specified in 'tag=value' form, which will be
          attached to data.

_D_e_t_a_i_l_s:

     Adding a 'tsp' attribute will ensure that the object returned
     inherits from class '"ts"', and adding a 'levels' attribute
     ensures that the returned object is a factor.

     For historical reasons (these names are used when deparsing),
     attributes '".Dim"', '".Dimnames"', '".Names"', '".Tsp"' and
     '".Label"' are renammed to '"dim"', '"dimnames"', '"names"',
     '"tsp"' and '"levels"'.

     It is possible to give the same tag more than once, in which case
     the last value assigned wins.  As other ways of assigning
     attributes, using 'tag=NULL' removes attribute 'tag' from '.Data'
     if it is present.
