Question

I am applying Aprior algorithm, and while plotting there is an error.

I have installed packages arules and arulesviz.

The data

Answer 1

I had this issue too and then realized that I forgot to load the library with

library(arulesViz)

after installing the package with:

install.packages("arulesViz")

Answer 2

This problem is caused by library installed incomplete(I guess it might put the wrong name(version) in the pack of arulesViz).

You can download https://cran.rstudio.com/bin/windows/contrib/3.3/seriation_1.2-1.zip manually,then use "r-studio menu -> tools -> install packages.." to install above zip file downloaded from the site.

Then try to redo install.packages("arulesViz") and library(arulesViz), it will be workable. Done.
