+## @deftypefn {Function File} {} loglogerr (@var{args})
+## This function produces two-dimensional plots on double logarithm axis 
+## with errorbars. Many different combinations of arguments are possible.  
+## The most used form is
+##
+## @example
+## loglogerr (@var{x}, @var{y}, @var{ey}, @var{fmt})
+## @end example
+##
+## @noindent
+## which produces a double logarithm plot of @var{y} versus @var{x} 
+## with errors in the @var{y}-scale defined by @var{ey} and the plot
+## format defined by @var{fmt}. See errorbar for available formats and 
+## additional information.
