Error saying missing sequenceID or eventID when trying to convert my data into cSPADE compatible format

Question

I'm unable to convert my data into cSPADE compatible format.

My data frame looks like-

 key type1 type2 type3 
 A-1  A     B     C
 B-2  P     Q    NA
 C-3  X     NA   NA

When I use, dataset1<- as(dataset, "transactions") and run-

rules<- cspade(dataset1, parameter = list(support = 0.4), control = list(verbose = TRUE))

It throws an error - 

Error in cspade(dataset1, parameter = list(support = 0.4), control = list(verbose = TRUE)) : slot transactionInfo: missing 'sequenceID' or 'eventID'

Answer 1

Try this:

source dataset in this format:

1 3 A B C
2 2 P Q    
3 1 X

the first column is for the id of sequence, the second columns is for the length of sequence and then the elements of sequences. Then:

data <- read_baskets(con = "./input_file.txt", info = c("sequenceID","eventID","SIZE"))
rules<- cspade(data, parameter = list(support = 0.4), control = list(verbose = TRUE))
