I have a vector with entries like 1,1,2,item1,item2 or 1,2,1,item1 that I
save as file_name.txt and then is transformed into a transaction by
calling:
data_ex - read_baskets(file_name.txt, sep=,, info=
c(eventID,sequenceID,SIZE))
as the first first three parts of the entry correspond to the eventID (my
customer number), the sequenceID (1 means the first shop for that customer,
2 the second and so on) and the SIZE (the number of items).
Then I create the inputs for the cspade function:
p - as(list(support=0.8), SPparameter)
q - as(list(verbose = TRUE, memsize=3000), SPcontrol)
and finally I call cspade:
cspade(data_ex, parameter = p, control = q, tmpdir = tempdir())
