ISI returns matrices with missing entries #4

Closed gobbios closed 4 years ago

gobbios commented 4 years ago

when using ISI(), the returned matrix (or matrices) may have interactions missing. For example,

data("devries98") res <- ISI(devries98)[[1]] res[c("k", "c"), c("k", "c")] k c k 0 0 c 0 0

versus the original devries98[c("k", "c"), c("k", "c")] k c k 0 2 c 2 0

Tied relationships (0/0, 1/1, 2/2 etc) are set to NA inside the ISI() function (because they are not relevant for the ranking). For the output all tied relationships were wrongly set to 0/0 (even non-zero ties), which had no effect on the ranking results.

The output should be correct now:

data("devries98") res <- ISI(devries98)[[1]] res[c("k", "c"), c("k", "c")] k c k 0 0 c 0 0

devries98[c("k", "c"), c("k", "c")] k c k 0 2 c 2 0
