[R] CSPADE error: system invocation error

[Sue Xu]

Hi,

I am trying to use the CSPADE function as part of the ArulesSequences package. When running with my own data I get a system invocation error, and also get the same when running the built in example with the zaki data:

> example(cspade)

And get the following error:

preprocessing ...Error in cspade(zaki, parameter = list(support = 0.4), control = list(verbose = TRUE)) : 
  system invocation failed

I read on a site saying that this error comes up when the support specified is too high, however I don't think this should happen with the example? Tried with support = 1e-10 anyway and the same error pops up.

I am running R 2.14.2 32-bit in Windows 7... but also downloaded 64-bit and the same error comes up. Have checked the package requirements and all seem to be okay. I have used the read_baskets function and it works fine.

Any help would be greatly appreciated

Regards
Sue
