Error occurs while using SPADE method in R
- by Yuwon Lee
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?
