     This correlation matrix was published in Jolliffe (2002, p.58). 
     The data consist of measurements of strength of reflexes at ten
     sites of the body, taken for 143 individuals. The variables come
     in five pairs, corresponding to right and left measurements on
     triceps, biceps, wrists, knees and ankles, respectively.

_F_o_r_m_a_t:

     It's a 10 x 10 correlation matrix, i.e. symmetric, and diagonal
     '1'. The five pairs of variables are (in this order) '"triceps.R",
     "triceps.L", "biceps.R", "biceps.L", "wrist.R", "wrist.L",
     "knee.R", "knee.L", "ankle.R", "ankle.L"'.
