Problem with reading specific variable column with read_pumas()

[pleasetellme]

Hi,

I would like to ask why the specific data column (D) would not be read if I include a specific group.

Without trying to read the variable D, the dataset is reading just fine.

Hope to hear back from you soon. Thank you.

Instead of dosegrp by using covariates it’s solved. Thank you.
