_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.
