R help - Jul 2012 - Problem with Apriori

Good morning

When I try to run an Apriori, I keep often the following message:

checking subsets of size 1Error in apriori(tr, parameter = list(supp 3e-05, conf
= 0.05, minlen = 2,  :
  internal error in trio library

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

Good morning,

1. What is your OS?

2. Which package do you use to perform the Apriori?

3. Without providing any reproducible code, it will probably be 
complicated to answer you.

Best Regards

Given the error message, a good guess is probably that the trio package 
is used.
The CRAN checks showed also some (maybe unrelated) problems with the 
package under R-devel recently. It is always a good idea to write to the 
package maintainer (hence CCing Holger Schwedner) - including 
reproducible code in the message, of course.

Best,
Uwe Ligges
