Hi, How do I remove a column formula but retain the values (without scripting)? I remember seeing an answer to this several months ago, maybe at the JMP summit, but I've forgotten and can't seem to figure it out.

Thanks,

Mike

Just remove the Formula column property. Values will be retained (as I remember it...).

Right-click on the column header and pick Column Info. There should be a list of properties. Select Formula and click the remove button.

Thanks. That worked.  I knew it was something simple, but couldn't remember it.

Can you answer this same question except using scripting?  I need to use a formula on a column, get a value, but not store the formula.

col << delete formula;

Documentation for all of these kind of items is available at

Or you could go without using a formula at all such as this:

dt<<New Column("Y",
<<Set Each Value(10+3*:x)
);

Of course that does depend on how complicated your formula is.

This works:

dt<<);

Now: Does anyone know how to replace the "dots" in the column with "0's" without using a formula?

I assume that when you are referring to "dots" that you are referencing the Missing Value character.  Interactively, the easiest way to replace all of the Missing Values is to paste a "0" (zero) into all of the cells.  The following steps will do that:

1. Go to one of the cells that has a missing value, and select the cell by clicking on it.

2. Enter into the cell a zero.

3. Copy the zero character into the paste buffer by selecting the cell and the right clicking and selecting "copy"

4. Go to a new cell for the same column that has a Missing Value and click on the cell.

5. Right click on the cell and select "Select Matching Cells"

6. Right click once again on the same cell, and select "Paste"

A zero "0" will then be pasted into all cells for that column that were Missing Values.

 

Or, you can use Recode

1. Click on the column header to select the column

2. Go to the pull down menu (or one of the column based red triangles) and select

     Cols==>Recode

3. Change the Missing Value displayed to a zero

4. Click on "Done"

5. Select "In Place"

 

 

To do the same action using JSL, the following script will work:

Names Default To Here( 1 );
dt = Current Data Table();
columnVector = dt << get rows where( Is Missing( dt:your column name ) == 1 );
dt:your column name[columnVector] = 0;

I'm trying to delete a column in JMP. However, the column to be deleted is used by another column in a formula. I can't find the syntax to remove the formula when I delete the column. Any ideas how to accomplish this would be appreciated. I have tried several things with no success:


col << Go To( :PC50);
Column("PC50") << delete formula;
dt <

col << Go To( :PC50);
Col ("PC50") << delete formula;
dt <

col << Go To( :"PC50");
Col("PC50") << delete formula;
dt <
col << Go To( :PC50);
col(:PC50) << delete formula;
dt <


and on and on...


What am I missing?

Here is an example of how to delete a column that is being referenced in the formula of another column.

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA\big class.jmp" );
dt << New Column( "LogHeight", formula( Log( :Height ) ) );

// Delete the formula in the column LogHeight
Column( "LogHeight" ) << delete formula;
dt << delete columns( "Height" );
