I am trying to run the cspade function in the arulesSequences package in R.
After I successfully read in my transactions using read_baskets, I try to
execute the cspade function against the transactions object I read in.
However, when I execute the command, I obtain an error: system invocation
failed. Specifically, here is the output.
preprocessing ... 1 partition(s), 1.2 MB [0.23s]
mining transactions ...Error in cspade(table, parameter = list(support 0.1),
control = list (verbose = TRUE)) :
system invocation failed
The presence of "mining transactions" indicates that the following
function
call in the cspade code is failing.
if (system2(file.path(exe, "spade"), args = c("-i",
file,
"-s", parameter at support, opt, "-e", nop,
"-o"), stdout = out))
stop("system invocation failed").
For reference, I can successfully generate sequences using the example zaki
dataset.
Does anyone have any idea why that command might be failing?
Thanks,
Stewart
