How to plot titles of items on arules plot?

Question

I have a list retail.hi of transactions that contains ids of items and I also have an info-df with ids and titles.

I'd like to see titles on the plot instead of ids. How can I do this?

The problem is that there are some ids that don't exist in my info-df, and for them i'd like to plot id instead of title.

I do plot like this:

plot(retail.hi, method = "graph", control = list(type = "items"))

Answer 1

You can replace the item labels in the labels column in

 itemInfo(retail.hi)

You probably need to match on your ids and then do this:

 iteminfo(retail.hi)$labels <- your_new_labels
