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

     Creates a wind profile in the standard atmospheric  notation. Each
     full barb = 10 m/s, half barb = 5 m/s,  and a filled triangle for
     50 m/s.  The maximum wind  speed that can be plotted without
     amending the program  is 65 m/s.

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

      plotwind(dataframe, size=5, ylim=c(1050, 100), legend=FALSE) 

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

dataframe: Data frame for sounding data, must have components for  wind
          speed `wspd', wind direction `dir',  and pressure `press'.

    size: change the thickness of the plotted lines

    ylim: plot extent, in units of pressure

  legend: explains wind barb strategy

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

     the dataframe must have components for wind speed `wspd',  wind
     direction `dir', and pressure `press'.   Missing values may be
     coded as either NA or 999. and are  not plotted.
     The standard atmospheric wind sybmol is a vector of fixed length 
     with barbs proportional to wind speed. A full barb for each 10
     m/s,   half barbs for 5 m/s and a triangular barb for 50 m/s.

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

     None - creates a plot.
