I'm currently mining sequence patterns using SPADE algorithm in R. SPADE is included in "arulesSequence" package of R. I'm running R on my CentOS 6.3 64bit.

For an exercise, I've tried an example presented in http://en.wikibooks.org/wiki/Data_Mining_Algorithms_In_R/Sequence_Mining/SPADE

When I tried to do "cspade(x, parameter = list(support = 0.4), control = list(verbose = TRUE))"

R says:

parameter specification:    
support : 0.4
maxsize :  10
maxlen  :  10

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

preprocessing ... 1 partition(s), 0 MB [0.096s]     
mining transactions ... 0 MB [0.066s]    
reading sequences ...Error in asMethod(object) : 's' is not an integer vector

When I try to run SPADE on my Window 7 32bit, it runs well without any error.

Does anybody know why such errors occur?
