Suppressing output

Question

I'm running a cluster analysis in which I want to feed in all the columns of my data table DT2WAY into the analysis, perform the analysis and then append the resulting allocation into 4 clusters to the right of that table, but without seeing any output. The following script does that for me, but leaves a dendrogram on the screen. Obviously I can simply delete it immediately afterwards, but I'd much prefer to suppress it altogether. How can I do that, please? style="font-size: 8pt; font-family: "Courier New"; color: black;"> style="font-size: 8pt; font-family: "Courier New"; color: black;">Ylist style="font-size: 8pt; font-family: "Courier New"; color: navy;">= style="font-size: 8pt; font-family: "Courier New"; color: black;"> {} style="font-size: 8pt; font-family: "Courier New"; color: navy;">; style="font-size: 8pt; font-family: "Courier New"; color: black;"> style="font-size: 8pt; font-family: "Courier New"; color: rgb(0, 0, 221);">for style="font-size: 8pt; font-family: "Courier New"; color: black;">( style="font-size: 8pt; font-family: "Courier New"; color: black;">i style="font-size: 8pt; font-family: "Courier New"; color: navy;">= style="font-size: 8pt; font-family: "Courier New"; color: teal;">1 style="font-size: 8pt; font-family: "Courier New"; color: navy;">, style="font-size: 8pt; font-family: "Courier New"; color: black;"> i style="font-size: 8pt; font-family: "Courier New"; color: navy;"><= style="font-size: 8pt; font-family: "Courier New"; color: rgb(0, 0, 221);">ncol style="font-size: 8pt; font-family: "Courier New"; color: black;">( style="font-size: 8pt; font-family: "Courier New"; color: black;">dt2way) style="font-size: 8pt; font-family: "Courier New"; color: navy;">, style="font-size: 8pt; font-family: "Courier New"; color: black;"> i style="font-size: 8pt; font-family: "Courier New"; color: navy;">++, style="font-size: 8pt; font-family: "Courier New"; color: black;"> style="font-size: 8pt; font-family: "Courier New"; color: rgb(0, 0, 221);">insert into style="font-size: 8pt; font-family: "Courier New"; color: black;">( style="font-size: 8pt; font-family: "Courier New"; color: black;">Ylist style="font-size: 8pt; font-family: "Courier New"; color: navy;">, style="font-size: 8pt; font-family: "Courier New"; color: black;"> style="font-size: 8pt; font-family: "Courier New"; color: rgb(0, 0, 221);">column style="font-size: 8pt; font-family: "Courier New"; color: black;">( style="font-size: 8pt; font-family: "Courier New"; color: black;">dt2way style="font-size: 8pt; font-family: "Courier New"; color: navy;">, style="font-size: 8pt; font-family: "Courier New"; color: black;"> ColName[i]))) style="font-size: 8pt; font-family: "Courier New"; color: navy;">; style="font-size: 8pt; font-family: "Courier New"; color: black;"> style="font-size: 8pt; font-family: "Courier New"; color: black;"> style="font-size: 8pt; font-family: "Courier New"; color: black;">dt2way style="font-size: 8pt; font-family: "Courier New"; color: navy;"><< style="font-size: 8pt; font-family: "Courier New"; color: black;"> Hierarchical Cluster( style="font-size: 8pt; font-family: "Courier New"; color: black;"> style=""> Y( style="font-size: 8pt; font-family: "Courier New"; color: rgb(0, 0, 221);">eval list style="font-size: 8pt; font-family: "Courier New"; color: black;">( style="font-size: 8pt; font-family: "Courier New"; color: black;">Ylist) ) style="font-size: 8pt; font-family: "Courier New"; color: navy;">, style="font-size: 8pt; font-family: "Courier New"; color: black;"> style="font-size: 8pt; font-family: "Courier New"; color: black;"> style=""> Method( style="font-size: 8pt; font-family: "Courier New"; color: purple;">"Ward" style="font-size: 8pt; font-family: "Courier New"; color: black;"> ) style="font-size: 8pt; font-family: "Courier New"; color: navy;">, style="font-size: 8pt; font-family: "Courier New"; color: black;"> style="font-size: 8pt; font-family: "Courier New"; color: black;"> style=""> Standardize( style="font-size: 8pt; font-family: "Courier New"; color: teal;">1 style="font-size: 8pt; font-family: "Courier New"; color: black;"> ) style="font-size: 8pt; font-family: "Courier New"; color: navy;">, style="font-size: 8pt; font-family: "Courier New"; color: black;"> style="font-size: 8pt; font-family: "Courier New"; color: black;"> style=""> Number of Clusters( style="font-size: 8pt; font-family: "Courier New"; color: teal;">4 style="font-size: 8pt; font-family: "Courier New"; color: black;"> ) style="font-size: 8pt; font-family: "Courier New"; color: navy;">, style="font-size: 8pt; font-family: "Courier New"; color: black;"> style="font-size: 8pt; font-family: "Courier New"; color: black;"> style=""> Save Clusters style="font-size: 8pt; font-family: "Courier New"; color: black;">) style="font-size: 8pt; font-family: "Courier New"; color: navy;">; style="font-size: 8pt; font-family: "Courier New"; color: black;">

From the JMP 8 docs:

Platform launches have an invisible option, which suppresses the showing of the window. Using this option on a Fit Model script suppresses both the model dialog and the results window.

When using this option, be careful to keep track of the window in the script and close it when the script is done with it, because the invisible windows use resources that must be manually freed.

Hi Jeff - that's perfect - many thanks!

Two quick additional questions, if I may:

(a) Is the "Invisible" keyword available for every platform?

(b) Do I need to delete anything afterwards?  That is, am I creating objects that I can't see (and which therefore really ought to be deleted simply for the sake of keeping a tidy workspace), or does using the "Invisible" option prevent the window from created in the first place?

David,

Try the Invisible keyword.

dt2way << Hierarchical Cluster( 
       Y( eval list(Ylist) ), 
       Method( "Ward" ), 
       Standardize( 1 ), 
       Number of Clusters( 4 ), 
       Save Clusters,
       Invisible
);
