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

     The function constructs a row-column design with subjects as rows
     and periods as columns. The design is incomplete, i.e. no subject
     gets all the treatments. The design is balanced for carryover
     effects but will in general not be a balanced block design.

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

     balminRMD(trt, n, p)

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

     trt: An integer >1 giving the number of treatments (products) to
          be tested. 

       n: An integer >1 giving the number of subjects (assessors) in
          the study. 

       p: An integer >1 giving the number of periods for each subject. 

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

     A necessary and sufficient condition for the existence of such a
     design is  that (trt-1)/(p-1) be a positive integer. In this case
     n = trt(trt-1)/(p-1).   In the resulting design the treatments are
     numbered 1,...,trt.  The entry (i,j)  of the design corresponds to
     the treatment the i-th subject gets in the j-th period.

_V_a_l_u_e:

     A matrix with n rows and p columns representing the experimental
     design.
