从列表中选择列组

Using an associative array, </CODE>I have a list containing the titles of column groups (common). I tried to use select column group with that but it doesn't work as is. What modifications do I need to make for this to work?</P><BR /><PRE><CODE class=" language-jsl">dt << select column group( common );

别理我！我明白了。呵呵！

For( g = 1, g <= N Items( common ), g++,
    dt << select column group( common[g] )
);

您还可以使用带有选择列组的列表，但您必须对其进行评估

Names Default To Here(1);

dt = Open("$SAMPLE_DATA/Cities.jmp");
dt << group columns("xy", {:X, :y});
dt << group columns("pollutants", :Ozone :: :Lead);

groupnames = {"xy", "pollutants"};
Eval(EvalExpr(dt << select column group(Expr(groupnames))));
