        text.default (x, y = NULL, labels = seq(along = x), adj = NULL, ...)

   AArrgguummeennttss::

       x, y: numeric vectors of coordinates where the text
             `labels' should be written.  If the length of `x'
             and `y' differs, the shorter one is recycled.

     labels: character or expression with the text to be writ-
             ten.

        adj: character or expression with the text to be writ-
             ten.

        ...: further graphical parameters (from `par'), such as
             `cex', etc.

   DDeessccrriippttiioonn::

        `text' draws the strings given in the vector `labels'
        at the coordinates given by `x' and `y'.  `y' may be
        missing since `xy.coords(x,y)' is used for construction
        of the coordinates.

   DDeettaaiillss::

        `labels' must be of type `character' or `expression'.
        In the latter case, quite a bit of mathematical nota-
        tion is available such as sub- and superscripts, greek
        letters, fractions, etc.

        `adj' allows adjustment of the text with respect to
        `(x,y)'.
