How to reference columns inside an imported .dtbin in an f(x) expression column?

[jooil kimParticipant]

I’m trying to reference a column within a .dtbin that was exported from R.

As an example, here’s the structure:

– There is the name of the .dtbin itself (“data”, from data.dtbin)

– Inside, I have a named data.frame (“CF4”)

– Then inside the data.frame, the column name I’m trying to specifically reference (“time”).

How do I write out a formatted reference to this “time” column to use in the definition of an expression (“f(x)”) data column?

Thanks!

You can add expressions directly into the same groups that contain the columns from the dtbin file.  Then you could just use the column names.

To refer to the column outside of the group, use path names, like any other column. Note that you will need a space between the name of the file and actions like division.

Does this help?

Yes, thanks for the info!

Can I advocate that this information be in the DG documentation for expressions?

Here is an article that I think helps.  Goes into more detail …
