Re: new column with all value set to zero

dt<<new column("All Zeros", set each value(0));

Re: new column with all value set to zero

Create your new column, then go to the Column Info for the column, click on the down arrow for "Initialize Data" and select "Constant".  Then enter in your "0" and clock OK

Re: new column with all value set to zero

For future searchers of a solution like this.

I wanted to do the same but with a character value like a file name for the source file upon import.  It seems like you have to declare Character in the New Column function to get it to work right.  Otherwise, it just populates with missing values.  Thanks.

This didn't work:

dt << New Column(colName, Set each value(fileName));

This did:

names default to here(1);
dt = current data table();

colName = "SourceFile";
fileName = dt << get name;

dt << New Column(colName, Character, Nominal, Set each value(fileName));
