As Table(matrix, <matrix 2, ...>, < <<invisible >, < <<private >, < <<Column Names({list }) >)
Description
Creates a new data tables from the matrix.
Returns
The new data table.
Argument
matrix
Any matrix.
<<invisible
Creates an invisible data table that hides the table from view but lists it in the JMP Home Window and Window menu.
<<private
Hides the table completely. Creating a private data table speeds the process of getting to the data; it does not save the computer from allocating the memory necessary to hold the data table data.
<<Column Names(list)
The list specified column names for the data. The argument is a list of quoted column names.
Col Stored Value(<dt>, col, <row>)
Description
Returns the data values stored in the column and disregards values assigned through column properties (such as Missing Value Codes).
Arguments
dt
Optional reference to a data table. If this value is not supplied, the current data table is used.
col
Name of the column.
row
(Optional) Row name or number. If this value is not specified, the current row is used.
Example
Suppose that the Missing Value Codes column property is assigned to the x1 column to treat “999” as a missing value. Another column includes a formula that calculates the mean. To use the value “999” instead of a missing value to calculate the mean, use Col Stored Value() in the formula:
Mean( Col Stored Value( :x1 ), :x2, :x3 )
Column(<dt>, "name", "formatted")
Column(<dt>, n)
Description
Gets a reference to the data table column.
Arguments
dt
Optional reference to a data table. If this is not supplied, the current data table is used.
name
A quoted string that is the name of the column.
formatted
A quoted string that returns the formatted string of the cell value.
n
The column number.
Column Name(n)
Description
Determines the name of the column specified by number.
Returns
The name of the nth column as an expression (not a quoted string).
Argument
n
The number of a column.
Count(from, to, step, times)
Description
Used for column formulas. Creates row by row the values beginning with the from value and ending with the to value. The number of steps specifies the number of values in the list between and including the from and to values. Each value determined by the first three arguments of the count function occurs consecutively the number of times that you specify. When the to value is reached, count starts over at the from value. If the from and to arguments are data table column names, count takes the values from the first row only. Values in subsequent rows are ignored.
Returns
The last value.
Arguments
from
Number, column reference, or expression. Count starts counting with this value.
to
Number, column reference, or expression. Count stops counting with this value.
step
Number or expression. Specifies the number of steps to use to count between from and to, inclusive.
times
Number or expression. Specifies the number of times each value is repeated before the next step.
Examples
/* the rows in the column named colname are filled with the series 0, 3, 6, 0,
... until all rows are filled */
For Each Row(:colname[row()]=count(0, 6, 3, 1))
/* the rows in the column named colname are filled with the series 0, 0, 3, 3, 6, 6, 0, ... until all rows are filled */
For Each Row(:colname[row()]=count(0, 6, 3, 2))
Notes
Count() is dependent on Row(), and is therefore mainly useful in column formulas.
Current Data Table(<dt>)
Description
Without an argument, gets the current (topmost) data table. With an argument, sets the current data table.
Returns
Reference to the current data table.
Argument
dt
Optional name of or reference to a data table.
Notes
Private tables cannot be made current with Current Data Table().
Data Table(n)
Data Table("name")
Get Data Table(<project(title|index|box|window),> name|index)
Description
Gets reference to the nth open data table or the table with the given name in a global variable.
Returns
Reference to the specified data table.
Argument
n
Number of a data table.
name
Quoted string, name of a data table.
Dif(col, n)
Description
Calculates the difference of the value of the column col in the current row and the value n rows previous to the current row.
Returns
The difference.
Arguments
col
A column name (for example, :age).
n
A number.
Dim(<dt|matrix>)
Description
Returns a row vector with the dimensions of the current data table, a specified data table, or a matrix. The dimensions are the number of rows and the number of columns and are listed in that order.
Arguments
dt
A data table.
matrix
A matrix.
Notes
If no argument is specified, the dimensions of the current data table are returned.
Get Data Table List(<Project(title|index|box|window>)
Description
Returns a list of all open data tables.
Notes
Use Project(0) to specify no project when running the expression in a project.
Lag(col, n)
Description
Returns for each row the value of the column n rows previous.
N Row(dt); NRow(matrix)
N Rows(dt); NRows(matrix)
Description
Returns the number of rows in the data table given by dt or in the matrix.
N Table()
Description
Returns the number of open data tables. Private tables are not included.
New Column("name", <"data type">, <"modeling type">, <Width(n)>, Format("format", width, precision), <Formula()>, <Set Values>, <Like(column reference)>, <actions>)
Description
Adds a new column named "name" after the last column in dt. Unless otherwise specified, columns are numeric, continuous, and 12 characters wide.
Returns
A column reference.
Notes
Can also be used as a message: dt<<New Column.
The Like() argument copies the data type, modeling type, format, formula, and other properties from the reference column into the new column.
See Also
dt<<New Column(name, <data type>, <modeling type>, <Format(format, width)>, <Formula()>, <Set Values({..., ..., })>, <Set Property(properties)>)
New Table("name", <visibility("invisible" | "private" | "visible")>, <actions>)
Description
Creates a new data table with the specified name.
Arguments
name
A quoted string that contains the name of the new table.
visibility
Optional quoted keyword. invisible hides the data table from view but lists it in the JMP Home Window and Window menu. private hides the table completely. visible shows the data table. "visible" is the default value.
Note: Creating a private data table speeds the process of getting to the data; it does not save the computer from allocating the memory necessary to hold the data table data.
actions
Optional argument that can define the new table.
Row()
Row() = y
Description
Returns or sets the current row number. No argument is expected.
Sequence(from, to, <step size>, <repeat times>)
Description
Produces an arithmetic sequence of numbers across the rows in a data table. The step size and repeat times arguments are optional, and the default value for both is 1.
Subscribe to Data Table List(<subscriber name|"">, <OnOpen(function)|OnClose(function)|OnRename(function)>)
Description
Subscribes to the data table list. You will be notified when a new data table has been added, closed, or renamed.
Subscript(a, b, c)
list[i]
matrix[b, c]
Description
Subscripts for lists extract the ith item from the list, or the bth row and the cth column from a matrix.
Suppress Formula Eval(Boolean)
Description
Turns off automatic calculation of formulas for all data tables.
Unsubscribe to Data Table List(<subscriber name>, <"OnOpen"|"OnClose"|"All">)
Description
Removes a subscription to the data table list that has been added through Subscribe to Data Table List().
Where(<dt>, clause)
Description
Filters and returns indices depending on the given clause. The clause can be a comparison function or a conditional statement. Columns, matrices, and lists can be mixed and matched within the same clause.
The indices returned by Where() are optimized for high performance on large lists, matrices, and columns.
Required Arguments
clause
A comparison function or conditional statement.
Optional Arguments
<dt>
Changes the current Data Table during the evaluation.
Examples
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << Clear Select << Select Rows(
Where( Col Max( :height, :age ) >= 68 )
);
dt << Clear Select << Select Rows(
Where( :height == Col Max( :height, :age ) )
);
