     A 433 by 218 matrix containing integers. 'dimnames(acl)[[2]]' are
     adjectives

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

     Each item is an adjective with five ordered answer categories  (0
     = completely disagree, 1 = disagree, 2 = agree nor disagree, 3 =
     agree, 4 = completely agree). The respondents were instructed to
     consider whether an adjective described their  personality, and
     mark the answer category that fits best to this description. The
     218 items constitute 22 scales (see table)  77 items of the 218
     items that constitute the ten scales were negatively worded. The
     negatively worded items are indicated by an asterisk in the
     \texttt{dimnames} and their item scores were reversed.
