Applying dictionaries to dfm

Dear All,

I m asking for support in the application of dictionaries.

Specifically, I am trying to calculate the proportion of words associated with a dictionary I created but I am only able to reckon the absolute number of such words in documents. It seems I am applying the argument scheme="prop" wrongly although it works with predefined Quanteda dictionaries.

Many thanks in advance for your help.

Warm regards,
