I am trying to learn about Sequence Mining, and I ran the following code from wikibooks as an example. The cspade function has taken over 30 minutes to run (and is still running) when the example shows that it should take less than a second. Does anyone know why this might be happening?

install.packages("arules")
install.packages("arulesSequences")

library(Matrix)
library(arules)
library(arulesSequences)

x <- read_baskets(con = system.file("misc", "zaki.txt", package = "arulesSequences"), info = c("sequenceID","eventID","SIZE"))
as(x, "data.frame")

s1 <- cspade(x, parameter = list(support = 0.4), control = list(verbose =TRUE))

  • Hmm maybe update your packages? The example works fine here. – lukeA Nov 12 '15 at 21:02
  • It says "All packages are up to date." I am using R version 3.2.2, arules version 1.2-1, and arulesSequences is version 0.2-11. – orangeteam2 Nov 13 '15 at 02:30
  • same here, plus Matrix_1.2-2 . – lukeA Nov 13 '15 at 09:14
  • Strange. I get `R> s1 <- cspade(x, parameter = list(support = 0.4), control = list(verbose =TRUE)) parameter specification: support : 0.4 maxsize : 10 maxlen : 10 algorithmic control: bfstype : FALSE verbose : TRUE summary : FALSE tidLists : FALSE preprocessing ... 1 partition(s), 0 MB [0.018s] mining transactions ... 0 MB [0.013s] reading sequences ... [0.016s] total elapsed time: 0.047s` so it is done in 47ms. (I use the same versions you do on Linux) – Michael Hahsler Nov 13 '15 at 19:27
  • When I updated to RStudio v0.99.764 Preview the code worked. Thank you for your suggestions! – orangeteam2 Nov 13 '15 at 21:57
