Moria Trautman posed a question in the LinkedIn JMP scripting group about the names of JMP icons that can be used in scripts. I have written a little widget that displays all the names I’ve been able to figure out, and it’s available here for the low, low price of $0.99.
I’ve figured out the names of 365 of the icons, and if anyone has discovered more of the icon names, I’ll update the widget to include them and send all purchasers a free update.
Run-only widget: $0.99
Does anybody know how to read a specific setting from the Preferences? I need to read the status of ‘Use JMP locale settings’ and if 0 then change to 1 and give the user a message to restart JMP.
Several people had helpful suggestions, but unfortunately it’s just not a trivial problem. It’s a surprisingly tricky problem.
First, by default
Show Preferences() only shows the preferences that you’ve taken to change. You need to use
Show Preferences(all) to see the defaults listed, too.
Show Preferences(SomeSpecificPreferenceHere), although a good guess, doesn’t actually work. You’ll just get the usual output for Show Preferences() without an argument.
Lesson: when you supply an argument JMP doesn’t understand, sometimes you get errors, but a lot of the time it’s just ignored, silently. You get no indication that you did something that doesn’t work. The only way you can be sure it was ignored is to try it again without the argument, or with a different argument, and check whether anything changed.
Show Preferences( [all] ) doesn’t return an expression. It returns missing. The information you need is echoed to the Log window, but it’s not returned as a string or an expression or a list or anything else you’d be able to do some work on. So you need to overcome that.
How to solve the basic problem
In JMP 9, you can Get Log(), which returns a list of strings, one for each line of whatever’s in the log. So to work efficiently, you need to
Clear Log() first, then
Show Preferences(all), then do
Well! Now you have a list of strings, and you need to find the item in that list that is relevant, so you need to put a
Contains() test inside a
It’s a string, so you have to transform it into an expression with
Parse() and some other bookkeeping, so that you can probe its argument with
Then check whether the argument is the desired one, and if not, change it, by editing the expression with
Substitute() and then immediately doing
Eval() on the result of that.
Now we need to let the user know we did something, and perhaps that they need to restart. So, put up a
New Window() with a
Text Box() saying that a preference has changed and they need to restart. Include a
Button Box() for “OK” that closes the alert window.
So, that’s the gist of the strategy.
Abstract the script
But, why write all this just for this one specific preference? Why not write it to check and if necessary change any preference?
So, start out with a couple globals that set the preference and the desired value.
But wait! Marianne’s example involves a numeric argument, but other preferences have text arguments; consider
Use JMP Locale Settings(0) vs.
Report Table Style("Plain"). So we need to make sure our script can work properly whether the particular preference takes a numeric or string value.
And while Marianne’s example requires a restart for the changed preference to take effect, most preferences do not. Might as well set a
restartNeeded=1 if it’s important, or
0 if it’s not.
In that alert window, we only need to tell them to restart if it’s important, not if it’s not, so let’s add an
If Box() around the
Text Box() that only shows the instruction if it’s needed.
If the preference was what we wanted in the first place, we should probably echo something to the Log window, just so we know it ran, if nothing else. We need a
Write() statement for that.
Which version of JMP?
But wait, there’s more! The
Get Log() command didn’t come along until JMP version 9. If you haven’t been able to upgrade yet, then you need to take another strategy to this whole problem.
There might be a better way to do this, but the only way I could find was to
Save Log() to a text file, then
Load Text File() to a string, then use
Substr() and a bunch of arguments with
Contains() to chop out the single preference we care about. From there, the script runs about the same way.
And we need to put all this inside a test for
JMP Version(), which returns a string, and usually we need to
Trim() it and then do an inequality test, e.g.
If( Trim( JMP Version() ) > "9", …), where the first argument is the
Get Log() strategy described first, and the second argument uses the
Save Log() strategy.
What about nested preferences?
Yet another problem! The script so far deals with top-level preferences with simple, single arguments, either numeric or character. But some preferences are trickier, e.g.,
Preferences( Fonts( English( Monospaced Font("Courier", 10) ) ) );
In this case, the
Parse() line will need to be more elaborate, and you’ll have to nest more
Arg()s around it to dig down to the particular setting value of interest. Conditioning for such a situation is left as an exercise for the reader, primarily because it’s a hassle, it’s not what Marianne needs, and the syntax of the
Preferences() command in JMP is arbitrary enough that we can’t really write code today that will be future-proof; we don’t know how deeply nested a given preference might be, nor what kind of arguments it might expect.
Nevertheless, the core of the script should be useful for anybody needing to query and change most preferences, and the elaboration necessary to adapt this script to a more deeply nested preference isn’t too complicated.
If you have any trouble with it, though, please feel free to contact us at Global Pragmatica LLC®; we’ll be happy to customize this script further for you at a nominal cost.
Purchase the code for $2
A finished, working, version-neutral script that has been tested on JMP 8 and 9 on Mac and Windows is available for purchase and immediate download for $2 US.
I am sending Marianne a coupon code for a complimentary copy, with my thanks for her intriguing question.
While the script itself might not be of immediate use to most readers, I hope that the strategies seen in the script will be of far greater value. Please contact me if you are in any way disappointed in the script, and I will arrange for an immediate bug-fix or refund upon receipt of your concerns.

One Proportion Test is a JMP script for performing a One Proportion Test quickly and easily.
I know I can calculate a sample size for a one proportion test in JMP, but how do I test for 1 proportion?
Karen Copeland, Ph.D., from Boulder Statistics promptly gave a helpful explanation of how to do it in JMP. JMP handles the problem quite capably, but you have to know where to find it and remember a bunch of details about how to use it:
To test one proportion in JMP I use the distribution platform. When you run a distribution for a nominal variable then in the red drop down menu there is an option for testing probabilities.
If you have a data table with a column for your proportion then you can proceed straight to the distribution platform. If not then first create a summary table with two columns. The first column would be your outcome such as Y/N or 0/1 and the he second column would be your frequency column of how many of each outcome you observed.
Testing of a proportion:
1. With a column of outcomes: First make sure that your column is of the nominal type. Second, use the distribution platform to create a distribution of the outcome. Under the red triangle drop down menu select “Test Probabilities” and a dialog box will appear with various options for testing your probabilities. Note, you need only fill in the one probability that you are interested in testing.
2. With a summary table for your outcomes: Again, make sure that your outcome column is of the nominal type. Second, use the distribution platform with your outcome column as the Y and the frequency column as the “Freq”. Then continue as above by selecting the test probabilities from the red triangle menu.
Note that you will also find confidence intervals for your proportions in the red drop down menu.
Boulder Statistics LLC and Global Pragmatica LLC are strategic allies, pairing Boulder Statistics’ analytical expertise with Global Pragmatica’s JMP scripting expertise to deliver outstanding solutions to our clients. When I saw Karen’s explanation, I immediately thought this would be a great opportunity to collaborate with her and build a JSL widget to make this easier.
This script is the result, and Global Pragmatica and Boulder Statistics are proud to make it available free, in an encrypted (run-only) script you can download today.
How to use One Proportion Test
You must license or download a demo copy of JMP software from SAS to use this JMP add-on script.
Launch the script. You are asked to choose a data table, which can be set up either of the two ways Dr. Copeland describes above. A dialog box requests the necessary column assignments. Click OK. At the bottom, fill in the details of the One Proportion Test. Use the Start Over button to restart the analysis with a different data table. For further help, see text at the top of the window and tooltips when hovering over buttons.
How encrypted scripts work (the free widget)
Encrypted scripts are run-only scripts. They are not human-readable, so you can’t modify them or adapt them for other purposes. If you would like to study the JSL, modify, or adapt the script, you should license the unencrypted version of this script instead.
Why pay for the unencrypted script?
Don’t! At least not right away… Start by “buying” the free widget. Try it out and see if you like it!
If you do, you might want to buy the full-price unencrypted script, so that you can modify, customize, or adapt the script for your own specialized needs, or so you can study a professional-quality script! This script demonstrates quite a few advanced scripting techniques, including:
- building an elegant, all-in-one-window user interface using display objects
- attaching scripts to buttons, radio buttons, column lists, etc.
- including a custom logo graphic
- implementing a different dialog box according to the user’s radio button choice
- opening, closing, and deleting display tree elements dynamically
- offering tips and help right in the window
- including email and web links for more information, sending feedback, etc.
- hiding globals—whether to protect intellectual property or to avoid cluttering up
- optimizing memory management and simplifying between-use value-clearing by storing problem-specific “globals” as entries in an
Associative Array()instead of in globals
You can read more about encrypted vs. unencrypted scripts offered by Global Pragmatica here.
One Proportion Test has been tested on JMP 8 for Mac and Windows as well as current beta versions of JMP 9 for Mac and Windows.
- In the second (no longer current) early adopter release of JMP 9 for Windows, you have to start the script manually. (This is not a problem in JMP 8 or later beta releases of JMP 9.) There are several ways to do this:
- press Ctrl-R, or
- click the Run Script button in the toolbar, or
- from the Edit menu, select Run Script

“Iterative Regression” is a script that Global Pragmatica LLC® developed for Ron Tanasichuk of the Canadian Department of Fisheries and Oceans, implementing his own interative regression technique. Performing the analysis is by hand is cumbersome and extremely slow and cumbersome. Automating the analysis reduces the processing time from weeks to minutes and eliminates the human error.
- for a single Y response and multiple X factors, fit all possible models having one and two factors (no interactions)
- for each model, exclude any outliers, and refit the model
- repeat fitting and excluding until there are no outliers for the model
- save the results from that model
- re-include all rows (unexclude all rows) and begin again with the next factor combination
Outliers are defined as rows where Abs(Studentized residuals > 2.5) AND (Y-hats > 4/n).
The script is compatible with JMP 7, 8, and 9 and has been thoroughly tested on Mac versions JMP 7, 8, and 9. A version tested on Windows as well will be available shortly.
