     Plotting objects of class 'Wave'.

     ## S4 method for signature 'Wave, missing':
     plot(x, info = FALSE, xunit = c("time", "samples"), 
         ylim = NULL, main = NULL, sub = NULL, xlab = NULL, ylab = NULL, 
         simplify = TRUE, nr = 1500, ...)
         
     plot.Wave.channel(x, xunit, ylim, xlab, ylab, main, nr, simplify, ...)

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

       x: Object of class 'Wave'.

    info: Logical, whether to include (written) information on the
          'Wave' object within the plot.

   xunit: Character indicating which units are used for setting up user
          coodinates (see 'par') and x-axis labeling. If 'xunit =
          "time"', the unit is time in seconds, otherwise the number of
          samples.

    ylim: The 'y' (amplitude) limits of the plot.

main, sub: A main / sub title for the plot.

xlab, ylab: Label for x-/y-axis.

simplify: Logical, whether the plot should be "simplified". If 'TRUE'
          (default), not all (thousand/millions/billions) of points
          (samples) of the  'Wave' object are drawn,  but the 'nr' (see
          below) ranges (in form of segments) within 'nr' windows of
          the time series.

          Plotting with 'simplify = FALSE' may take several minutes
          (depending on the number of samples in the 'Wave') and output
          in any vector format may be really huge.

      nr: Number of windows (segments) to be used _approximately_ (an
          appropriate number close to 'nr' is selected) to 'simplify'
          (see above) the plot. Only used if 'simplify = TRUE' and the
          number of samples of 'Wave' object 'x' is larger.

     ...: Further arguments to be passed to the underlying plot
          functions.

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

     Function 'plot.Wave.channel' is a helper function to plot a single
     (left!) channel; in particular it is _not_ intended to be called
     by the user directly.
