Add values above a particular value to Missing Value Codes

SpannerHead — Thu, 12 Dec 2024 17:17:24 GMT

I looked through the forum and I didn't see this posted. I want to add all values in a data table that are greater than a particular value to be included as missing value codes. The approach I was thinking of was to iteratively define all those values in a list and then add that list to the iteration like this.

Column( dt, colNames[i] ) << set property ("Missing Value Codes", {999, -999, 1e+13, 1.5e13, 2e+13, 3e+13, 4e+13, 5e+13, 6e+13, 1e+30, 2e+30, 3e+30, -5.5e+29, 9e+33});

Anyone figure this out? If not, I'll work something out and post that.

Until we get this, you have to use something like you have described

Names Default To Here(1); 

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

limit = 55;
m = dt[0, "height"];
high_rows = Loc(m > 55);

Column(dt, "height") << Set Property("Missing Value Codes", As List(m[high_rows]));

Write();

Added an iterative loop and colouring for the eliminated cells off to the races.

Names Default To Here(1); 

dt = Current Data Table();

colnames = dt << get column names( numeric,string );
meanlist = {};
For( i = 1, i <= N Items( colnames ), i++,	
m = dt[0, colnames[i]];
high_rows = Loc(m > 1000000);

column(dt,colnames[i]) << Set Property("Missing Value Codes", As List(m[high_rows]));
column(dt,colnames[i]) << Color Cells("Red", high_rows);

Write();
	
);
