R help - Aug 2011 - cspade error

Hi,

I'm using the cspade function from the arulesSequences package on linux and
keep getting the error:
"Error in makebin(data, file) : 'sid' invalid"

any information on how to solve this would be much appreciated.

Thanks.

  Please provide a reproducible example (hint: read the posting guide,
and/or <http://tinyurl.com/reproducible-000>)

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=",",
infoc("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())
