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

     Creates a SKEW-T, log p diagram with dry-bulb temperature and 
     dewpoint temperature traces versus (log) pressure. Optionally
     plots the vertical wind profile using wind barbs.

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

      plotsonde(dataframe, skewT=TRUE, winds=FALSE, site="", title="",
                windplot=NULL, s=3, col=c(1, 2), ... ) 

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

dataframe: R dataframe of a radiosonde dataset  (as created by
          'getsonde') 

   skewT: Logical value.  If false, will not plot the  SKEW-T, log p
          diagram. 

   winds: Logical value.  If false, will not plot the winds profile. 

    site: Optional character to add to plot title. 

   title: Title for plot (must be a character value). 

windplot: 4X1 numeric vector that gives the position of wind profile 
          plot (next to SKEW-T diagram).  Only used if it is desired to
          have this plot in a different position.  Generally, the 
          default NULL is used and the placement is chosen 
          automatically.  

       s: Size of winds profile plot.  

     col: Usual plotting parameter. 

     ...: Other optional plotting parameters. 

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

     No value returned.  Creates a plot.
