Dear R-help, I am interested in plotting some pedigrees and came across the kinship2 package. What follows is an example of the pedigrees I am working with.
Now, when running ## check package availability if(!require(kinship2)) install.packages('kinship2') require(kinship2) ## data to plot d <- structure(list(FamilyID = c("1", "1", "1", "1", "1", "1", "1", "1", "1"), PatientID = structure(c(2L, 3L, 5L, 11L, 12L, 15L, 16L, 17L, 6L), .Label = c(" 1", " 2", " 3", " 4", " 5", " 6", " 7", " 9", "10", "11", "13", "14", "18", "20", "23", "24", "25", "27", "28", "29", "30", "31", "33", "34", "35", "37", "38", "39", "41", "43", "45", "50", "62", "63", "64", "65", "66", "67", "85", "88"), class = "factor"), FatherID = structure(c(1L, 1L, 6L, 1L, 5L, 6L, 1L, 7L, 6L), .Label = c("0", "1", "10", "11", "13", "2", "23", "27", "28", "3", "33", "34", "35", "38", "5", "62", "64", "66", "9"), class = "factor"), MotherID = structure(c(1L, 1L, 7L, 1L, 14L, 7L, 1L, 5L, 7L), .Label = c("0", "10", "18", "2", "24", "29", "3", "30", "33", "34", "39", "4", "43", "5", "6", "63", "65", "9"), class = "factor"), Sex = structure(c(2L, 1L, 1L, 2L, 2L, 2L, 1L, 2L, 2L), .Label = c("Female", "Male"), class = "factor"), AffectionStatus = structure(c(1L, 1L, 2L, 1L, 2L, 2L, 1L, 2L, 2L), .Label = c("1", "2"), class = "factor")), .Names = c("FamilyID", "PatientID", "FatherID", "MotherID", "Sex", "AffectionStatus" ), row.names = c(NA, 9L), class = "data.frame") ## plotting ped <- with(d, pedigree(PatientID, FatherID, MotherID, Sex, affected = AffectionStatus, famid = FamilyID)) ## Error in pedigree(PatientID, FatherID, MotherID, Sex, affected = AffectionStatus, : ## Value of 'dadid' not found in the id list 1/0 1/0 1/2 1/0 1/2 I get an error. My sessionInfo() is at the end. I was wondering if someone could help me to dissect what the cause of this error is and how it can be fixed. Thank you very much for your help.
