我有一個模板數據框，其中包含209列標記為1-209的列。 客戶通常會轉發給我包含合併列的數據集，例如，可以在新數據集中添加第2列和第3列（標記為“ 2 + 3”）。
如何提取新數據集中的列並將其用作公式以使列與模板數據框中的列相同？ 我知道JMP具有合併功能，但是如何編寫一個腳本來提取所有列名並將其轉換為公式以對齊兩個數據集。
我已在此電子郵件中附加了模板和目標數據集的外觀。
這是一個簡單的腳本，在合併的列上展開。注意：“模板數據”表中的列名有誤。列名95出現兩次。第二個應該是98。
Names Default To Here( 1 );
// 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 )));
你好@MikeDereviankin ，
我不確定我是否完全了解您的需求，但我是這樣認為的，並做了大約一天的工作。 （我不如程序員或精通JSL的人快@txnelson ，他知道自己的東西！）。 我也沒有嘗試過他的代碼，但是我以不同的方式思考（我認為）。
下面的代碼將從“目標”數據表中帶有“ +”的列名中獲取數據，在“模板”數據表中創建一個新的公式列，將這些特定列加在一起。 然後，將它們移動到數據表中的適當位置，並刪除添加在一起的原始列。 它還將從列中刪除公式屬性。
因為它們是數字，所以花了大約一天的時間尋找正確的方式來調用列名稱。 不用Eval（）和Parse（）等命令就能使用字符名稱來引用它們要容易得多。有關如何執行此操作）。 我在其中放置了一個Wait（）命令，但是您可能不需要它。
Names Default To Here( 1 );
//defines the two data tables, they must be open already and named appropriately
dt_target = Data Table( "Target" );
dt_template = Data Table( "Template" );
//This gets the column names for each table
target_col_names = dt_target << get columnnames( Numeric, string );
template_col_names = dt_template << get column Names( Numeric, string );
//This tests the column names in the target data table to see if there is a "+" and if so puts that column name in the target_col_keep list
target_col_keep = {};
For( i = 1, i <= N Cols( dt_target ) - 1, i++,
If( Contains( target_col_names[i], "+" ) != 0,
Insert Into( target_col_keep, target_col_names[i] )

);
//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.

//this step moves the newly created column after the second column of the sum. Comment out if you don't want to move them.

);希望這可以幫助！，
