Description

Combines data tables dt and Data Table side to side.

Returns

A data table.

Required Arguments

With(Data Table(name))

Specifies the data table to join with the active table.

"Private"

Specifies a quoted keyword that opens the data table without displaying it in a data table window.

"Invisible"

Specifies a quoted keyword that hides the data table. Use this argument to keep the data table hidden but use it in a subsequent expression. The data table is displayed in the Home Window’s Window List and the Window > Unhide list.

Select(columns)

Selects the data table to join with the active table.

Select With(columns)

By Matching Columns(column1=column2)

Selects columns in both tables whose values and data types match.

"Cartesian"

Joins two tables using a Cartesian fashion, where it forms a new data table consisting of all possible combinations of the rows from two original data tables. JMP crosses the data in the first table with the data in the second to display all combinations of the values in each set.

"By Row Number"

Joins the two tables side by side.

"Merge Same Name Columns"

Data from the second table replaces the data of the same name columns in the original table. Note that missing values in the first table are replaced by nonmissing values in the second.

"Match Flag"

Determines whether the Match Flag column is created when you are matching by column.

Copy Formula(Boolean)

Includes formulas from the main table and/or the second table in the output columns.

Suppress Formula Evaluation(Boolean)

Prevents JMP from evaluating columns’ formulas during the creation of the new table.

"Update"

Column data from the second table change the data of the same name columns in the original table. The results are displayed in a new data table. Note the following: JMP does not replace data with missing values; the output table uses the same columns as the original table. Thus, when you use "Update", Select Columns, the "Update" option is available only when joining by row number or by matching columns.

Drop Multiples(Boolean, Boolean)

Specifies that you want the new table to contain only one row for each name. Applies only when matching by columns.

Include Non Matches(Boolean, Boolean)

Includes non-matching columns in the main table and new data table. Applies only when matching by columns.

"Preserve Main Table Order"

Maintains the order of the original data table in the joined table, instead of sorting by the matching columns.

Output Table Name(name)

Specifies the name of the joined table. If you do not specify a name, JMP names the data table Untitled # (for example, Untitled 1).

dt<<Journal

Makes a journal from the data table. Only the data grid is included, not notes, variables, or scripts.

Note

Journals that are created in JMP 14 or later might contain compressed matrix data for large matrices. If you have JSL scripts that open journals and extract data from them, you might need to use the Get Journal message (which does not compress the matrices) rather than saving the journal to disk with the Journal message.

See Also

See dt<<Get Journal

Create Journals in the Scripting Guide

dt<<Journal Link(<Save(<path>)|Embed()>, <Button Name(<name>)>))

Adds a link to the data table in the current journal. If a journal does not exist, a new one is created.

Optional Arguments

Example

The following script creates a data table view and report in one window. The data table is placed in a data browser box. The width of that box is set to 800 pixels. Because auto stretch is turned off, the data table view remains 800 pixels wide even if you stretch the right border of the window.

dtA = Open( "$SAMPLE_DATA/Semiconductor Capability.jmp", invisible );

nw = New Window( "Example",

	H List Box(

		V List Box( dtbox = dtA << New Data Box() ),

		dtA << Distribution(

			Continuous Distribution( Column( :NPN1 ) ),

			Continuous Distribution( Column( :PNP1 ) )

		)

	)

);

dtbox << Set Stretch( "Off", "Off" ) << Set Width( 800 );

dt<<New Data View

Opens a duplicate of the data table. The second data table is identical to and linked to the original data table, so that any changes made in one are reflected in the other. Closing either data table also closes the other and all references to the data tables are deleted.

This can be useful to show an invisible data table.

dt<<New Script(name, script)

dt<<Set Property(name, script)

Creates a new table property (also called a table script) using the quoted name that stores the specified script.

Use New Script() or Set Property() rather than the deprecated New Property() and New Table Property().

Example

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

dt << Set Property( "Bivariate Example", Bivariate( Y( :weight ), X( :height ), Fit Line ) );

dt<<New Table Variable(name, number)

dt<<Set Table Variable(name, number)

Creates a new table variable with the quoted name and the number.

dt<<Next Selected

Scrolls data table down to show the next selected row that is not already in view.

dt<<Optimize Display

Forces the data table to remeasure all of its columns and zoom to the best-sized window.

dt<<Original Order

Restores saved order of columns in dt.

dt<<Paste Column Properties

Pastes multiple lists of column properties to multiple columns. Optionally, you can specify a list of target columns instead of selecting them in the data table.

Example

dt = Open( "$SAMPLE_DATA/Tiretread.jmp" );

dt << Copy Column Properties( {:MODULUS, :ELONG} );

dt2 = New Table( "test it",

	New Column( "T1", numeric, continuous ),

	New Column( "T2", numeric, continuous ),

	New Column( "T3", numeric, continuous ),

	Add Rows( 10 )

);

dt2 << Paste Column Properties( {:T1, :T3} );

// pastes the column properties from MODULUS and ELONG to T1 and T3

dt<<Predictor Screening

dt<<Screen Predictors

Description

Used to identify strong predictors.

Example

dt = Open( "$SAMPLE_DATA/Boston Housing.jmp" );

obj = dt << Predictor Screening(

	Y( :mvalue ),

	X( :crim, :indus, :chas, :nox, :rooms, :age, :distance, :radial )

);

dt<<Previous Selected

Scrolls data table up to show the previous selected row that is not already in view.

dt<<Print Window(<"Show Dialog">)

Prints the window. If the optional named argument "Show Dialog" is specified, the print window is displayed. Otherwise, the window is printed to the default printer using the current settings, and no print window is displayed.

dt<<Select Randomly(n|p|Sample Size(n)|Sampling Rate(p))

Randomly selects the given percentage p of the rows in the data table, or the number of rows n. If you specify an argument with a keyword, numbers between 0 and 1 represent a percentage, and numbers larger than 1 represent a number of rows.

dt<<Select Rows([row1, row2, ...])

Selects the rows given in the list of row numbers.

dt<<Select Script Group(<group name|{group1, group2, ...}>)

dt<<Set Name(name)

Description

Specifies a name for the table. The name argument is quoted.

Returns

The data table name as a quoted string.

Notes

A change was made to the Set Name message so that now the new table name is returned as a quoted string. In previous releases, Set Name returned a scriptable data table object. As a result of this change, JMP scripts might need to be updated for the desired result to be returned. For example, rewrite the following script:

dt = Open( "$SAMPLE_DATA/Big Class.jmp" ) << Set Name( "Test" );

Separate the messages so that dt represents the data table instead of “Test”:

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

dt << Set Name( "Test" );

The result is the same as in previous releases but will run successfully in both earlier and newer versions of JMP.

dt<<Set Property(name, script)

See dt<<New Script(name, script).

dt<<Set Label Columns(column(s), ...)

dt<<Set Label Columns

Turns on the Label attribute for the specified columns. If no columns are listed, it turns the Label attribute off.
