Launches a Shiny App that provides an interactive interface to the visualizations of the arulesViz
package.
The app allows users to mine rules based on all or just subsets of features, sort by criteria (lift, support, confidence) and visualize
using network graph, grouped bubble and scatter plots.
Users filter rules to target only those with a certain variable on the RHS or LHS of the rule.
Rule mining is computed using the apriori algorithm from arules
.

|
dataset |
data.frame, this is the dataset that association rules will be mined from. Each row is treated as a transaction. Seems to work
OK when a the S4 transactions class from |
bin |
logical, |
vars |
integer, how many variables to include in initial rule mining |
supp |
numeric, the support parameter for initializing visualization. Useful when it is known that a high support is needed to not crash computationally. |
conf |
numeric, the confidence parameter for initializing visualization. Similarly useful when it is known that a high confidence is needed to not crash computationally. |
