arules package (apriori)
...orithm to my data. The set of data contains missing values and consists in a combination of continuous and categorical variables.
After discretizing the continuous variables, I wrote the following instruiction to perform Apriori, but I obtained the following error message:
> rules <- apriori(dd_new,parameter=list(supp=0.5, conf=0.9, target="rules"))
Erreur dans asMethod(object) :
column(s)12345679101112131415162123242553not a factor
Does this have any relation with the missing values?
Thanks.
Cordially,
