_D_e_s_c_r_i_p_t_i_o_n:

     Retrieve a grob or a descendant of a grob.

_U_s_a_g_e:

     grid.get(gPath, strict = FALSE, grep = FALSE, global = FALSE,
              allDevices = FALSE)

     getGrob(gTree, gPath, strict = FALSE, grep = FALSE, global = FALSE) 

_A_r_g_u_m_e_n_t_s:

   gTree: A gTree object.

   gPath: A gPath object. For 'grid.get' this specifyies a grob on the
          display list.  For 'getGrob' this specifies a descendant of
          the specified gTree. 

  strict: A boolean indicating whether the gPath must be matched
          exactly. 

    grep: A boolean indicating whether the 'gPath' should be treated as
          a regular expression.  Values are recycled across elements of
          the 'gPath' (e.g., 'c(TRUE, FALSE)' means that every odd
          element of the 'gPath' will be treated as a regular
          expression). 

  global: A boolean indicating whether the function should affect just
          the first match of the 'gPath', or whether all matches should
          be affected. 

allDevices: A boolean indicating whether all open devices should be
          searched for matches, or just the current device. NOT YET
          IMPLEMENTED. 

_V_a_l_u_e:

     A grob object.

     'grob', 'getGrob', 'addGrob', 'removeGrob'.

_E_x_a_m_p_l_e_s:

     grid.xaxis(name="xa")
     grid.get("xa")
     grid.get(gPath("xa", "ticks"))

     grid.draw(gTree(name="gt", children=gList(xaxisGrob(name="axis"))))
     grid.get(gPath("gt", "axis", "ticks"))
