+## @deftypefn {Function File} {} cut (@var{x}, @var{breaks})
 ## Create categorical data out of numerical or continuous data by
 ## cutting into intervals.
 ##
-## If BREAKS is a scalar, the data is cut into that many equal-width
-## intervals. If BREAKS is a vector of break points, the category has
-## length(BREAKS)-1 groups.
+## If @var{breaks} is a scalar, the data is cut into that many
+## equal-width intervals.  If @var{breaks} is a vector of break points,

 ##
-## Returns a vector of the same size as X telling which group each point
-## in X belongs to.  Groups are labelled from 1 to the number of groups;
-## points outside the range of BREAKS are labelled by NaN.
