_D_e_s_c_r_i_p_t_i_o_n:

     A series of approximately yearly angiographic examinations of
     heart transplant recipients.  The state at each time is a grade of
     coronary artery vasculopathy (CAV),  a deterioration of the
     arterial walls.

_U_s_a_g_e:

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

     A data frame containing 2846 rows.  There are 622 patients, the
     rows are grouped by patient number and ordered by years after
     transplant, with each row representing an examination and
     containing additional covariates.

        'PTNUM'  (numeric)    Patient identification number
          'age'  (numeric)    Recipient age at examination (years)
        'years'  (numeric)    Examination time (years after transplant)
         'dage'  (numeric)    Age of heart donor (years)
          'sex'  (character)  sex (0=male, 1=female)
        'pdiag'  (character)  Primary diagnosis (reason for transplant)
                              IHD=ischaemic heart disease, IDC=idiopathic dilated cardiomyopathy.
       'cumrej'  (numeric)    Cumulative number of acute rejection episodes
        'state'  (numeric)    State at the examination.
                              State 1 represents no CAV, state 2 is mild/moderate CAV
                              and state 3 is severe CAV.  State 4 indicates death.
