Is there anyway to use arulesViz to visualize itemsets returned by opusminer?

Hello!

First of all, thank you so much for making arulesViz, it is a great package!

I know that I can use arulesViz to visualize itemsets returned by arules, but I'm wondering if I can make the same visualizations with itemsets returned by the opusminer package? From what I can see, opusminer returns list of itemsets quite similar in format to that returned by generatingItemsets(rules), but without the support parameter for each.

Thank you very much for any help!

I just looked at opusminer. If the itemsets have no support then you can calculate it from the data using code like:

quality(your_itemsets) <- interestMeasure(your_itemsets, transactions = your_trans)

Now the visualization should work.
