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

     Retrieve the number of rows (genes) and columns (arrays) for an
     BeadLevelList.

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

     ## S3 method for class 'BeadLevelList':
     dim(x)

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

       x: an object of class 'BeadLevelList'

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

     BeadArray data objects share many analogies with ordinary matrices
     in which the rows correspond to spots or genes and the columns to
     arrays. These methods allow one to extract the size of microarray
     data objects in the same way that one would do for ordinary
     matrices.

     A consequence is that row and column commands 'nrow(x)', 'ncol(x)'
     and so on also work.

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

     Numeric vector of length 2. The first element is the number of
     rows (genes) and the second is the number of columns (arrays).

_A_u_t_h_o_r(_s):

     Gordon Smyth, modified by Mike Smith for BeadLevelList object

_S_e_e _A_l_s_o:

     'dim' in the base package.
