A function that extracts individually irrelevant cases for sufficiency from an object of class "qca".

1 | ```
cases.suf.iir(results, outcome, neg.out=FALSE, sol = 1)
``` |

`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 |

`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. |

# Import your data. For example:

# 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)
# Get the intermediate solution:
sol_yi <- minimize(SCHF, outcome = "EXPORT",
conditions = c("EMP","BARGAIN","UNI","OCCUP","STOCK", "MA"),
incl.cut = .9,
include = "?",
details = TRUE, show.cases = TRUE, dir.exp = c(0,0,0,0,0,0))
# Return individually irrelevant cases for sufficiency for the parsimonious solution:
cases.suf.iir(results = sol_yp, outcome = "EXPORT")
# Return individually irrelevant cases cases for sufficiency for the intermediate solution:

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