Set NA as the default value for your nested ifelse() commands

self.komplett$iri1 <- ifelse(self.komplett$VC01_01 == 5,
                             "1" ,
                             ifelse(self.komplett$VC01_01 != 5,
                                    "0",
                                    NA
                                    )
                             )
