This is probably really simple, but I've been through the scripting guide and I've searched the community discussions without any luck so here goes:
I'm trying to copy a comple data table with values, column properties and all. Is there a command for this? I tried to hack something together:
dt=current data table(); colNames = dt << Get Column Names( String ); ndt = New Table("Plotting Data", /*invisible,*/); For (i=1, i <= NCols(dt), i++, New Column(colNames[i]); colProps = Column(dt, colNames[i]) << Get Column Properties; Column( ndt, colNames[i]) << Add Column Properties( colProps ); ); ndt << Add Rows(NRows(dt)); For (j=1, j <= NCols(dt), j++, colVals = Column(dt, colNames[j]) << Get values; Column(ndt, colNames[j]) << Set values( colVals ); );
However besides being overly complicated for something rather simple, it won't copy character data because data type is apparently not included in column properties.
Another way is to subset the table with all rows and all columns.
dt = Open( "$SAMPLE_DATA\Big Class.jmp" ); dt_copy = dt << Subset( All rows, Selected columns only( 0 ) );
