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

     Plot of a Walter & Lieth climatic diagram of a station.

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

     diagwl(dat, est = "", alt = NA, per = "", margen = c(4, 4, 5, 4), mlab = "",
       pcol = "#005ac8", tcol = "#e81800", pfcol = "cyan", sfcol = "#0eb6d7",
       shem = FALSE, ...)

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

     dat: Monthly climatic data on which the diagram will be plotted.

     est: Name of the climatological station

     alt: Altitude of the climatological station

     per: Period of observation

  margen: Margins vector for the plot (to be passed to 'par').

    mlab: Month labels for the X axis:

          "_e_n": Month initials in English.

          "_e_s": Month initials in Spanish.

          _O_t_h_e_r: Numeric labels (1-12).

    pcol: Color pen for precipitation.

    tcol: Color pen for temperature.

   pfcol: Fill color for probable frosts.

   sfcol: Fill color for sure frosts.

    shem: Set to 'TRUE' for southern hemisphere stations.

     ...: Other graphic parameters

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

     Climatic data must be passed as a 4x12 matrix of monthly (January
     to December) data, in the following order:

     _R_o_w _1: Mean precipitation

     _R_o_w _2: Mean maximum daily temperature

     _R_o_w _3: Mean minimum daily temperature

     _R_o_w _4: Absolute monthly minimum temperature

     This last row is only used to determine the probable frost months
     (when monthly values are equal or lower than 0C). If 'shem=TRUE',
     the diagram will begin the plot with the July data, to keep the
     summer period in the central zone of the graphic.

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

     No value is returned by this function.

_R_e_f_e_r_e_n_c_e_s:

     WALTER H & LIETH H (1960): Klimadiagramm Weltatlas. G. Fischer,
     Jena.

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

     'plot', 'par'

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

       data(cli.dat)
       diagwl(cli.dat,est="Example station",alt=100,per="1961-90",mlab="en")
