CSPADE method in R throws ERROR: no slot of name “transactionInfo” for this object of class “transactions”

Question

I get error in R when running the following method for CSPADE algorithm (finding association rules in transactions):

x <- read_baskets(con = system.file("misc", "zaki.txt", package = "arulesSequences"), info = c("sequenceID","eventID","SIZE"))

s1 <- cspade(x, parameter = list(support = 0.4), control = list(verbose = TRUE))
parameter specification:
support : 0.4
maxsize :  10
maxlen  :  10

algorithmic control:
bfstype  : FALSE
verbose  :  TRUE
summary  : FALSE
tidLists : FALSE

preprocessing ...
Error in typeof(x) : 
  no slot of name "transactionInfo" for this object of class "transactions"

"x" is a transaction object and it gets successfully created but for some reason the cspade method does not work (even on its classic data set which is provided in its documentation)

Answer 1

Probably too late but for next readers, I think this bug appeared after an upgrade of the package.

Just add :

attributes(x)$transactionInfo <- x@itemsetInfo

after creating x with read_baskets()
