A function that matches typical cases and individually irrelevant cases with regards to sufficiency for each INUS condition.

1 2	matches.suf.typiir(results, outcome, term = 1, neg.out=FALSE, sol=1, max_pairs = 5)

`results`	An object of class "qca".
`outcome`	A character string with the name of the outcome in capital letters. When performing pimdata of the sufficient solution for the negated outcome one must only use the `minimize()` result from the sufficiency analysis of the negated outcome in the argument `results`. Changing the name in the argument `outcome` or using a tilde is not necessary.
`term`	A numeric vector where the first number indicates the number of the term according to the order in the "qca" object.
`neg.out`	Logical. Should the negated outcome be used?
`sol`	A numeric vector where the first number indicates the number of the solution in case of model ambiguity according to the order in the "qca" object.
`max_pairs`	Maximum number of pairs to extract.

minimize

# Import your data. For example:

data(SCHF)

# Get the parsimonious solution:


sol_yp <- minimize(SCHF, outcome = "EXPORT",
                conditions = c("EMP","BARGAIN","UNI","OCCUP","STOCK", "MA"),
                incl.cut = .9, 
                include = "?", 					   
                details = TRUE, show.cases = TRUE)


# Match typical cases and individually irrelevant cases for each conjunct 
# for the first term (default) of the parsimonious solution and return only the best 3 pairs:

matches.suf.typiir(results = sol_yp, outcome = "EXPORT", max_pairs=2)

# Get the parsimonious solution for the absence of the outcome:

sol_nyp <- minimize(SCHF, outcome = "EXPORT", neg.out = TRUE,
                conditions = c("EMP","BARGAIN","UNI","OCCUP","STOCK", "MA"),
                incl.cut = .9, 
                include = "?", 					   
                details = TRUE, show.cases = TRUE)

# Match typical cases and individually irrelevant cases for each conjunct for 
# the first term of the second parsimonious solution for the absence of the outcome:

matches.suf.typiir(results = sol_nyp, outcome = "EXPORT", neg.out = TRUE, term = 1, sol = 2)

# since it has only one condition, it cannot find pairs based on the INUS principle!
