The support measure
In the last exercise, you dug into the several transactions of the Online_trx
dataset. Now it's time for you to figure out the support metrics of a few specific items.
Previously, you already found the number of transactions containing the HERB MARKER ROSEMARY
item. In this exercise, you will find the support of that same product alongside the HERB MARKER THYME
item at different support thresholds using the apriori()
function of the arules
package.
The transactional object Online_trx
is loaded in the workspace.

Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Determine the support of both items with support 0.1
support_rosemary_thyme =
apriori(Online_trx,
parameter = list(target = "___",
supp = 0.1),
___ = list(___ =
c("HERB MARKER ROSEMARY",
"HERB MARKER THYME"))
)
# Summary of the object
