how to add a new formula with JSL?all i use the samlpe which named thickness.JMP to produce a new file by summary。 but i don not know to how to add one formula with JSL in summary table。Re: how to add a new formula with JSL?That's a typo. I have pointer to data table called dtIn.Re: how to add a new formula with JSL?I am assuming that you have a pointer to your data table called
dtInput
but not one called
dtIn
Re: how to add a new formula with JSL?I am stuck with a simialr issue. I perform division operation in one column and then need to transpose the table.Running into issue while I try to do this.
dtIn << New Column("Max Size ",Character,format("best",8),Formula(
:Name("Max Size") = (2500/:Min Size))
);
//check for empty columns and delete if any
dt = Current Data Table();
names = dt << Get Column Names();
dt1 = dt << Missing Data Pattern(columns(Eval(names)), invisible);
n = N Row(dt1);
For(i = N Col(dt), i >= 1, i--,
If(Col Sum(Column(dt1, i + 3)) < n,
Remove From(names, i)
)
);
Try(dt << delete columns(names));
Close(dt1, nosave);
//Get all coulmn names
allcolnames = dt << get column names(string);
show(allcolnames);
for (i = 1, i <= nitems(allcolnames), i++,
column(dt, allcolnames[i]) << data type(Character,"Nominal");
);
But getting an error becuase of the formula -
Cannot convert argument to a number [or matrix] 1 times At rows: 2 Operation: Divide, 2500 / /*###*/:Min Size/*###*/
Formula evaluation errors have been ignored
Re: how to add a new formula with JSL?Your formula involves division. It requires numeric data columns for this compuation. Your result is set up for a new column with the character data type. If that is what you want, then wrap the division inside the Char() function to satisfy the data type.
Re: how to add a new formula with JSL?i want to calculate " Thickness 01/N rows ". JSL is below, that is right? dt << New Column( "New formula column", Character, Formula( :Name( "Thickness 01) / :Name( "N rows"));Re: how to add a new formula with JSL?To create the summary table first and then add a formula column to it, save a reference to the table when you create it:
//Save reference to the newly created summary table.
dt = Data Table( "Thickness" ) << Summary( Group( :Bar ), N, Mean( :Thickness 01 ) );
//Send a message to the new table to create the new column.
dt << New Column( "New formula column",
Character,
Formula(
If( :Name( "Mean(Thickness 01)" ) > 0.04,
"normal",
"thin"
)
)
);
