arules package apriori() fn error message XXXX
Hi everybody,
I am using the apriori() fn in the arules package and am encountered an error.
rules <- apriori(rdayst,parameter = list(support = 0.01, confidence = 0.6))
"You chose a very low absolute support count of 0. You might run of memory."
I assume this is related to the value of .01 specified for the support
= argument. If so, what is a safe and reliable max value for

predictive apriori
Dear list members,
I know that there is the arules package with the implementation of the
apriori algorithm. However i want to use the "predictive apriori" instead.
These algorithm can mine as rules as i want and there is an implementation
on weka.
There is some implementation on R?

Other time it works fine on the same data. What can be the reason for this?

arules package: using image() deliveres unexpected results
Dear Collegues,
it seems like there is a problem with the image()-method in the package arules.
Using an ordninary matrix works fine:
image(matrix(rnorm(200), 10, 20), axes = FALSE, col=brewer.pal(9, "Blues") )
delivers an image with blue colors and no axes.
Using an object of the class "associations" (arules package) does not work:
image(items(ta.eclat), axes = FALSE,

How to make sure self-heal backlog is empty ?
Hello list,
I'm not sure what to look for here, not sure if what I'm seeing is the
actual "backlog" (that we need to make sure is empty while performing a
rolling upgrade before going to the next node), how can I tell, while
reading this, if it's okay to reboot / upgrade my next node in the pool ?
Here is what I do for checking :

ARULES --> Filtering Rules by RHS
Dear Colleagues,
I would like to only inspect rules that contain a certain label substring on the rhs. In this special case the item labels are built like this:
<itemtype>_<itemvalue> e.g. "Artikelgruppe_E0815" what I want to do is only show rules where "Artikelgruppe" is contained in the rhs - has anybody an idea how this could work?
Sincerely

How to make sure self-heal backlog is empty ?
Mine also has a list of files that seemingly never heal. They are usually isolated on my arbiter bricks, but not always. I would also like to find an answer for this behavior.
