我有一个模板数据框，其中包含标记为 1-209 的 209 列。 通常，客户会向我转发包含组合列的数据集，例如，在新数据集中，可能会添加第 2 列和第 3 列（标记为“2 + 3”）。
如何提取新数据集中的列并将其用作公式以使模板数据框中的列相同？ 我知道 JMP 有一个组合函数，但我如何编写一个脚本来提取所有列名称并将其转换为公式以对齐两个数据集。
我已在这封电子邮件中附加了模板和目标数据集的外观。
你好@MikeDereviankin ,
我不确定我是否完全理解你的目的，但我想是的，并为此工作了大约一天。 （作为一名程序员，我的速度或 JSL 悟性不如@tx尼尔森，他知道他的东西！）。 我也没有尝试他的代码，但我以不同的方式思考它（我认为）。
下面的代码将从“目标”数据表中获取其中包含“+”的列名称，在“模板”数据表中创建一个新的公式列，将这些特定列添加在一起。 然后，它将它们移动到数据表中的正确位置，并删除添加在一起的原始列。 它还从列中删除公式属性。
花了大约一天的时间才找到调用列名称的正确方法，因为它们是数字。 拥有角色名称以便在没有 Eval() 和 Parse() 命令等的情况下引用它们要容易得多。我相信更好的人可以使其更优雅，但这是有效的（至少是我解释你问的方式）了解如何做到这一点）。 我在其中放置了一个 Wait() 命令，但您可能不需要它。

//This loops through the items in target_col_keep to make new columns and add formulas.
//The complicated part of As Column(Num(Word(Eval(EvalExpr(Expr()))))) basically converts the number names to a reference-able column.
//The extra +1 is there because of the first column in the dt_template data table -- it offsets the column numbers on down the line in <BR />//reference to the target data table.
//The first word command gets only the first column of the added up to the "+", hence Word(1,...)
//The second word command gets only the second word after the "+", hence Word(2,...)
//The new columns are added to the end of the data table.

这是一个扩展组合列的简单脚本。注意：模板数据表中的列名称有错误。列名称 95 出现两次。第二个应该是98。

// Point to the 2 data tables....assumption is they are open
dtTemplate = Data Table( "Template_Template" );
dtTarget = Data Table( "Target_Target" );
// Create a template data table with just the column names
dtHeader = dtTemplate << subset( selectd rows( 0 ), selected columns( 0 ) );
dtHeader << select where( Row() > 0 );
dtHeader << delete rows;
// Change the column data type to match in incoming target data
dtHeader:Column 1 << datatype( character );
// Concatenate the data together. JMP will match all columns with the
// same name, and create new columns for ones that don't have a match
dtInterim = dtHeader << concatenate( dtTarget );
// Loop across the new columns and assign the values back to the columns
// the values need to be in
For( i = N Cols( dtHeader ) + 1, i <= N Cols( dtInterim ), i++,
start = Num( Word( 1, Column( dtInterim, i ) << get name, "+" ) );
end = Num( Word( 2, Column( dtInterim, i ) << get name, "+" ) );
For( k = start, k <= end, k++,
Column( dtInterim, Char( k ) )[1] = Column( dtInterim, i )[1]

);
// Delete the extra columns
dtInterim << delete columns( index(N Cols( dtHeader ) + 1, N Cols( dtInterim )));
