I Was able to figure out how to create my object using the
"read_baskets"
function but when I run the "cspade" function I receive the following
error
(running in RStudio)
...
4 -> 1 2 -> 1 -> 1 -- 1 1
3 -> 1 2 -> 1 -> 1 -- 1 1
3 4 -> 1 2 -> 1 -> 1 -- 1 1
3 4 -> 1 -> 1 -> 1 -- 1 1

Error in .class1(object) : object 's1' not found

But if I run in R (alone) it works just fine.  Any idea why I can' t seem to
run in RStudio or what I might have to do in RStudio?

For anyone who has used the "arulesSequences" Package how do I start
with
raw data (*.csv file) and convert into a sequence object to run the cSPADE
function.  The package example use zaki dataset which has already been
converted.  When I state raw data how should I structure my csv file?

A web example  or RPubs link?

For example
Seq_1	{E,B}, {C}, {T}
Seq_2 	(E,M}, {C}, {B,E,V,T}
Seq_3 	{E},{C},{T}
