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

     The profile along a transect and/or an interpolated raster
     distribution within the cross-sectional area of the transect is
     drawn.

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

     plotTransect(id, rasterField = NULL, velPlot = FALSE, flow = "magnitude")

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

      id: the name of the transect.

rasterField: the raster field of interest, see the 'type' component in
          'tran.dat'.

 velPlot: a logical; if 'TRUE' velocity raster data is plotted.

    flow: the velocity component types to use where '"magnitude"' is
          the principle direction of flow and '"longTran"' is the
          longitudinal and transverse directions.

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

     If the 'rasterField' argument is missing a profile is plotted
     along the transect.  The horizontal axis is representative of the
     distance between transect vertices and  the vertical axis the
     distance from the vertex origin, 'v.origin', positive upward.  The
     profile along a transect is by default based on the interpolated
     surface, 'data.tin'.  If the 'data.tin' component of 'srvy.dat' is
     'NULL' the function will attempt to  access imported profile data
     in 'prof'.

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

     Fisher, J. C.

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

     'mba.points', 'filled.contour', 'tran.profile'

_E_x_a_m_p_l_e_s:

     data(confluence)
     plotTransect("T1")
     plotTransect("T1", rasterField = "SpCond (uS/cm)")
     plotTransect("T1", velPlot = TRUE, flow = "longTran")
