Row Functions
Row Functions
Adding a row function to a formula lets you reference specific rows or cells within specific rows. See the
JMP Scripting Guide for details about syntax.
Sequence
Produces an arithmetic sequence of numbers across the rows in a data table, where the start value,
ending limit, and increment are specified as arguments.
Count
Creates a list of 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 you specify with the times argument. When the to value is reached, Count starts over at the from
value.
Also, you can add the times argument with the insert button ( ) on the keyboard. This argument is
one by default, but repeats the count process as many times as you specify, as illustrated by the Count4
column in the data table in Figure C.1. To add any argument to the Count function, highlight the
argument preceding the one you want to enter and either type a comma or use the insert button ( )
on the formula editor keypad.
The columns in the data table below result from the following formulas:
• Count (1, 9, 2) gives Count 1
• Count (1, 9, 3) gives Count 2
• Count (1, 9, 9) gives Count 3
• Count (1, 9, 3, 3) gives Count 4
Figure C.1 Example of the Count Function
C Formula Functions Reference
The Count function is useful for generating a column of grid values. For example, the following
formulas create a square grid of increment NRow() (the Row function that gives the total number of
rows in the data table) and axes that range from –5 to 5:
Count (–5, 5, Root(NRow()))
Count (–5, 5, Root(NRow(), Root(NRow())))
